What does the Bible say about the soul and eternal life?

Scripture states that no man can sustain his own soul; this verse reminds believers of their utter dependence on God for life. In Psalm 22:29, 'none can keep alive his own soul' indicates that all spiritual life originates from God, and we require His continuous intervention to maintain that life. Jeremiah 10:23 declares, 'O Lord, I know that the way of man is not in himself: it is not in man that walketh to direct his steps,' reinforcing our need for divine guidance.

Furthermore, in John 3:3, Jesus asserts, 'Except a man be born again, he cannot see the kingdom of God,' signifying the necessity of a new birth, a spiritual awakening wrought by God's grace. Spiritual life is a gift, and without God's sustaining hand, we are incapable of preserving it ourselves. Our prayers, inclinations towards God, and spiritual vitality are products of God's initiative in our lives.
