They both proclaim for us to be merciful reciprically towards all due to the mercy of GOD.
you wish they had different messages.
OK, just point out the verse where the Quran talks about
Muslims being merciful to unbelievers "due to the mercy of GOD":
Quran 9
1. A declaration of immunity from God and His Messenger to the polytheists with whom you had made a treaty.
2. So travel the land for four months, and know that you cannot escape God, and that God will disgrace the disbelievers.
3. And a proclamation from God and His Messenger to the people on the day of the Greater Pilgrimage, that God has disowned the polytheists, and so did His Messenger. If you repent, it will be better for you. But if you turn away, know that you cannot escape God.
And announce to those who disbelieve a painful punishment.
4. Except for those among the polytheists with whom you had made a treaty, and did not violate any of its terms, nor aided anyone against you. So fulfill the treaty with them to the end of its term. God loves the righteous.
5. When the Sacred Months have passed,
kill the polytheists wherever you find them. And capture them, and besiege them, and lie in wait for them at every ambush. But if they repent, and perform the prayers, and pay the alms, then let them go their way. God is Most Forgiving, Most Merciful.
6. And if anyone of the polytheists asks you for protection, give him protection so that he may hear the Word of God; then escort him to his place of safety. That is because they are a people who do not know.
7.
How can there be a treaty with the polytheists on the part of God and His Messenger, except for those with whom you made a treaty at the Sacred Mosque? As long as they are upright with you, be upright with them. God loves the pious.
8. How? Whenever they overcome you, they respect neither kinship nor treaty with you. They satisfy you with lip service, but their hearts refuse, and most of them are immoral.
9. They traded away God's revelations for a cheap price, so they barred others from His path. How evil is what they did.
10. Towards a believer they respect neither kinship nor treaty. These are the transgressors.
11. But if they repent, and perform the prayers, and give the obligatory charity, then they are your brethren in faith. We detail the revelations for a people who know.
12. But if they violate their oaths after their pledge, and attack your religion,
then fight the leaders of disbelief—they have no faith—so that they may desist.
13.
Will you not fight a people who violated their oaths, and planned to exile the Messenger, and initiated hostilities against you? Do you fear them? It is God you should fear, if you are believers.
14.
Fight them. God will punish them at your hands, and humiliate them, and help you against them, and heal the hearts of a believing people.
15. And He will remove the anger of their hearts. God redeems whomever He wills. God is Knowledgeable and Wise.
16. Or do you think that you will be left alone, without God identifying which of you will strive, and take no supporters apart from God, His Messenger, and the believers? God is well Aware of what you do.
17. It is not for the polytheists to attend God’s places of worship while professing their disbelief. These—their works are in vain, and in the Fire they will abide.
18. The only people to attend God’s places of worship are those who believe in God and the Last Day, and pray regularly, and practice regular charity, and fear none but God. These are most likely to be guided.
19. Do you consider giving water to pilgrims and maintaining the Sacred Mosque the same as believing in God and the Last Day and striving in God’s path? They are not equal in God’s sight. God does not guide the unjust people.
20. Those who believe, and emigrate, and strive in God’s path with their possessions and their persons, are of a higher rank with God. These are the winners.
21. Their Lord announces to them good news of mercy from Him, and acceptance, and gardens wherein they will have lasting bliss.
22. Abiding therein forever. With God is a great reward.
23. O you who believe!
Do not ally yourselves with your parents and your siblings if they prefer disbelief to belief. Whoever of you allies himself with them—these are the wrongdoers.
24. Say, “If your parents, and your children, and your siblings, and your spouses, and your relatives, and the wealth you have acquired, and a business you worry about, and homes you love, are more dear to you than God, and His Messenger, and the struggle in His cause, then wait until God executes His judgment.” God does not guide the sinful people.
25. God has given you victory in numerous regions; but on the day of Hunayn, your great number impressed you, but it availed you nothing; and the land, as spacious as it was, narrowed for you; and you turned your backs in retreat.
26. Then God sent down His serenity upon His Messenger, and upon the believers; and He sent down troops you did not see; and He punished those who disbelieved. Such is the recompense of the disbelievers.
27. Then, after that, God will relent towards whomever He wills. God is Forgiving and Merciful.
28. O you who believe! The polytheists are polluted, so let them not approach the Sacred Mosque after this year of theirs. And if you fear poverty, God will enrich you from His grace, if He wills. God is Aware and Wise.
29.
Fight those who do not believe in God, nor in the Last Day, nor forbid what God and His Messenger have forbidden, nor abide by the religion of truth—from among those who received the Scripture—until they pay the due tax, willingly or unwillingly.
30. The Jews said, “Ezra is the son of God,” and the Christians said, “The Messiah is the son of God.” These are their statements, out of their mouths. They emulate the statements of those who blasphemed before. May God assail them! How deceived they are!
31. They have taken their rabbis and their priests as lords instead of God, as well as the Messiah son of Mary. Although they were commanded to worship none but The One God. There is no god except He. Glory be to Him; High above what they associate with Him.
32. They want to extinguish God’s light with their mouths, but God refuses except to complete His light, even though the disbelievers dislike it.
33. It is He who sent His Messenger with the guidance and the religion of truth, in order to make it prevail over all religions, even though the idolaters dislike it.
34. O you who believe! Many of the rabbis and priests consume people's wealth illicitly, and hinder from God’s path. Those who hoard gold and silver, and do not spend them in God’s cause,
inform them of a painful punishment.
35. On the Day when they will be heated in the Fire of Hell, then their foreheads, and their sides, and their backs will be branded with them: “This is what you hoarded for yourselves; so taste what you used to hoard.”
36. The number of months, according to God, is twelve months—in the decree of God—since the Day He created the heavens and the earth, of which four are sacred. This is the correct religion. So do not wrong yourselves during them.
And fight the polytheists collectively, as they fight you collectively, and know that God is with the righteous.
37. Postponement is an increase in disbelief—by which those who disbelieve are led astray. They allow it one year, and forbid it another year, in order to conform to the number made sacred by God, thus permitting what God has forbidden. The evil of their deeds seems good to them. God does not guide the disbelieving people.
38. O you who believe!
What is the matter with you, when it is said to you, “Mobilize in the cause of God,” you cling heavily to the earth? Do you prefer the present life to the Hereafter? The enjoyment of the present life, compared to the Hereafter, is only a little.
39.
Unless you mobilize, He will punish you most painfully, and will replace you with another people, and you will not harm Him at all. God has power over all things.
40. If you do not help him, God has already helped him, when those who disbelieved expelled him, and he was the second of two in the cave. He said to his friend, “Do not worry, God is with us.” And God made His tranquility descend upon him, and supported him with forces you did not see, and made the word of those who disbelieved the lowest, while the Word of God is the Highest. God is Mighty and Wise.
41.
Mobilize, light or heavy, and strive with your possessions and your lives in the cause of God. That is better for you, if you only knew.
42. Had the gain been immediate, and the journey shorter, they would have followed you; but the distance seemed too long for them. Still they swear by God: “Had we been able, we would have marched out with you.” They damn their own souls, and God knows that they are lying.
43. May God pardon you! Why did you give them permission before it became clear to you who are the truthful ones, and who are the liars?
44. Those who believe in God and the Last Day
do not ask you for exemption from striving with their possessions and their lives. God is fully aware of the righteous.
45. Only those who do not believe in God and the Last Day ask you for exemption. Their hearts are full of doubts, so they waver in their doubts.
