B4 a man can believe, he must be given seeing eyes, spiritually Jn 6 40
40 And this is the will of him that sent me, that every one which seeth the Son, and believeth on him, may have everlasting life: and I will raise him up at the last day.
That seeing requires life/regeneration, otherwise man is dead, blind as a bat spiritually
Sorry faith precedes life
Romans 1:17 (LEB) — 17 For the righteousness of God is revealed in it from faith to faith, just as it is written, “But the one who is righteous by faith will live.”
John 3:16 (LEB) — 16 For in this way God loved the world, so that he gave his one and only Son, in order that everyone who believes in him will not perish, but will have eternal life.
1 Peter 1:8–9 (LEB) — 8 whom, although you have not seen, you love; in whom now you believe, although you do not see him, and you rejoice greatly with joy inexpressible and full of glory, 9 obtaining the goal of your faith, the salvation of your souls.
Romans 10:9–10 (LEB) — 9 that if you confess with your mouth “Jesus is Lord” and believe in your heart that God raised him from the dead, you will be saved. 10 For with the heart one believes, resulting in righteousness, and with the mouth one confesses, resulting in salvation.
1 John 5:13 (LEB) — 13 These things I have written to you who believe in the name of the Son of God, in order that you may know that you have eternal life.
John 3:15 (KJV 1900) — 15 That whosoever believeth in him should not perish, but have eternal life.
