“And without faith it is impossible to please God, because anyone who comes to him must believe that he exists and that he rewards those who earnestly seek him.” (Heb. 11:6 NIV)
The verse at top tells you that you must have faith in order to please God. And that faith involves two things you must believe: First, believe that He exists, and second, believe that He rewards those who earnestly seek Him. Can you do those two things?
Believe that He exists
You can’t actually see God because He is Spirit (John 4:24) and is invisible. “No one has ever seen God; the only God, who is at the Father's side, he has made him known.” (John 1:18)
But God reveals Himself to us in other ways.
By His Son, Jesus — “He is the radiance of the glory of God and the exact imprint of his nature, (Heb. 1:3).”; “He is the image of the invisible God, the firstborn of all creation.” (Col. 1:15); “And the Word became flesh and dwelt among us, and we have seen his glory, glory as of the only Son from the Father, full of grace and truth.” (John 1:14)
By what He has made — “For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse.” (Rom. 1:20); “The heavens declare the glory of God, and the sky above proclaims his handiwork.” (Psalm 19:1)
By His written Word, the Bible — “In the beginning was the Word, and the Word was with God, and the Word was God.” (John 1:1)
2. Believe that He rewards those who earnestly seek Him
“I the Lord search the heart and test the mind, to give every man according to his ways, according to the fruit of his deeds.” (Jer. 17:10)
“But seek first the kingdom of God and His righteousness, and all these things shall be added to you.” (Matt. 33)
“Whatever you do, work at it with all your heart, as working for the Lord, not for human masters, since you know that you will receive an inheritance from the Lord as a reward. It is the Lord Christ you are serving.” (Col. 3:23-24)
