Oh, there indeed appear to be many contradictions in the Scripture. But the Word of God is True.
As Jesus said, many things are taught so the people will not understand, because they refuse to repent and quit sinning.
“To you it has been given to know the mystery of the kingdom of God; but to those who are outside, all things come in parables, 12 so that
‘Seeing they may see and not perceive, And hearing they may hear and not understand;
Lest they should turn, And their sins be forgiven them.’ ”
- Mark 4:11-12
So, even in the churches, many to do understand the Word of God, and misinterpret or twist the Scripture to come up with crazy doctrines such as OSAS, Eternal Forgiveness and a mythical escape to the spirit realm to avoid the necessary tribulation that will perfect them.
As Jesus said -
"Let them alone. They are blind leaders of the blind. And if the blind leads the blind, both will fall into a ditch.” - Matt 15:14
May we be among those who "hunger and thirst for righteousness" that we may be filled with all wisdom and knowledge of Christ through the Spirit, coming to maturity, until we enter in the fullness of God.
