John 17:3 “And this is eternal life, that they know you the only true God, and Jesus Christ whom you have sent.”
In the words of Jesus, eternal life is knowing God, and Jesus Christ – who is God.
Hebrews 11:6 “And without faith it is impossible to please [God], for whoever would draw near to God must believe that he exists and that he rewards those who seek him.”
God rewards those who seek him. With what? Himself.
