Jn 5:24, Jn 6:57-58, Phil 3:20-21, Col 3:4, 2 Cor 3:18, 1 Jn 3:2

Those who believe in Jesus as the Son of God and the Christ, whom God has sent, have eternal life. (Jn 5:24, Jn 6:57-58)

Jn 5:24 Verily, verily, I say unto you, He that heareth my word, and believeth on him that sent me, hath everlasting life, and shall not come into condemnation; but is passed from death unto life.

Jn 6:57 As the living Father hath sent me, and I live by the Father: so he that eateth me, even he shall live by me. 58 This is that bread which came down from heaven: not as your fathers did eat manna, and are dead: he that eateth of this bread shall live for ever.

When Christ comes again, we are transformed into the likeness of Christ's glorious body. (Phil 3:20-21, 1 Cor 15:45-49, Col 3:4, 2 Cor 3:18, 1 Jn 3:2)

Phil 3:20 For our conversation is in heaven; from whence also we look for the Saviour, the Lord Jesus Christ: 21 Who shall change our vile body, that it may be fashioned like unto his glorious body, according to the working whereby he is able even to subdue all things unto himself.

1 Cor 15:45 And so it is written, The first man Adam was made a living soul; the last Adam was made a quickening spirit. 46 Howbeit that was not first which is spiritual, but that which is natural; and afterward that which is spiritual. 47 The first man is of the earth, earthy; the second man is the Lord from heaven. 48 As is the earthy, such are they also that are earthy: and as is the heavenly, such are they also that are heavenly. 49 And as we have borne the image of the earthy, we shall also bear the image of the heavenly.

Col 3:4 When Christ, who is our life, shall appear, then shall ye also appear with him in glory.

2 Cor 3:18 But we all, with open face beholding as in a glass the glory of the Lord, are changed into the same image from glory to glory, even as by the Spirit of the Lord.

1 Jn 3:2 Beloved, now are we the sons of God, and it doth not yet appear what we shall be: but we know that, when he shall appear, we shall be like him; for we shall see him as he is.
