John 3:36 – Whoever believes in the Son has eternal life, but whoever rejects the Son will not see life, for God’s wrath remains on him.”
Jesus says that those who believe in him have (not will have) everlasting life. To receive eternal life is to join in God’s life, which by nature is eternal. Thus, eternal life begins at the moment of spiritual rebirth.
Proverbs 3:5-6 Trust in the LORD with all your heart and lean not on your own understanding; (6) in all your ways acknowledge him and he will make your paths straight.
