You can never please God without faith, without depending on Him. Anyone who wants to come to God must believe that there is a God and that He rewards those who sincerely look for Him.
Hebrews 11:6 (TLB)

We live by faith and not by sight.
II Corinthians 5:7 (CEB)

You are saved by God’s Grace because of your faith. This salvation is God’s Gift. It’s not something you possessed.
Ephesians 2:8 (CEB)

If you have faith, you will receive whatever you pray for.
Matthew 21:22 (CEB)

You may know that there is nothing wrong with what you do, even from God’s point of view, but keep it to yourself; don’t flaunt your faith in front of others who might be hurt by it. In this situation, happy is the man who does not sin by doing what he knows is right.
Romans 14:22 (TLB)

But anyone who believes that something he wants to do is wrong shouldn’t do it. He sins if he does, for he thinks it is wrong, and so for him it is wrong. Anything that is done apart from what he feels is right is sin.
Romans 14:23 (TLB)
