without me ye can do nothing.
Jn 15:4-5
4 Abide in me, and I in you. As the branch cannot bear fruit of itself, except it abide in the vine; no more can ye, except ye abide in me.
5 I am the vine, ye are the branches: He that abideth in me, and I in him, the same bringeth forth much fruit: for without me ye can do nothing.
Before we can bear fruit, we must be in Christ, and Christ in us, So before we can believe [Faith] we must be in Christ and again, Christ in us by His Spirit, For Faith/ Believing is a Fruit of His Spirit Gal 5:22
22 But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith,
We know believers are in Christ before they believe, because Christ says of His Sheep before they Hear and Believe and follow Him this Jn 10:16
16 And other sheep I have, which are not of this fold: them also I must bring, and they shall hear my voice; and there shall be one fold, and one shepherd.

Yes if He has them, they are in Him. Also all believers were ordained to Eternal Life before they believed Acts 13:48
48 And when the Gentiles heard this, they were glad, and glorified the word of the Lord: and as many as were ordained to eternal life believed.
For they were ordained to Eternal Life because they were heirs of promise Gal 3:29
And if ye be Christ's, then are ye Abraham's seed, and heirs according to the promise.
Heb 6:17
Wherein God, willing more abundantly to shew unto the heirs of promise the immutability of his counsel, confirmed it by an oath:
And to all the Heirs of Promise its given to them to believe on Christ Phil 1:29. They had been ordained to Eternal Life by being in Union with Christ their Mediator Head before the world began, when this Eternal Life was promised Titus 1:1-2
Paul, a servant of God, and an apostle of Jesus Christ, according to the faith of God's elect, and the acknowledging of the truth which is after godliness;
2 In hope of eternal life, which God, that cannot lie, promised before the world began;
Here it was promised to Christ and His Seed Chosen in Him Eph 1:4. Remember Gal 3:16-19
16 Now to Abraham and his seed were the promises made. He saith not, And to seeds, as of many; but as of one, And to thy seed, which is Christ.
17 And this I say, that the covenant, that was confirmed before of God in Christ, the law, which was four hundred and thirty years after, cannot disannul, that it should make the promise of none effect.
18 For if the inheritance be of the law, it is no more of promise: but God gave it to Abraham by promise.
19 Wherefore then serveth the law? It was added because of transgressions, till the seed should come to whom the promise was made; and it was ordained by angels in the hand of a mediator.
Now the Promised Inheritance in Vs 18 is Eternal Life, and the Promise was initially made to Christ in Eternity Past, indicated in Vs 16,17,19, God's Promise was made to Christ before the world began Titus 1:2, and those Chosen in Him before the foundation Eph 1:4, they were ordained with Him as joint Heirs with Christ Rom 8:17, and they believe Acts 13:48.
