Without FAITH it is IMPOSSIBLE to please God. Faith is belief. It doesn't say "without repentance....without confession....without water baptism...it is impossible to please God". NO. It says "Without FAITH (BELIEF) it is IMPOSSIBLE to please God, for he that comes to God MUST BELIEVE that He is, and that He is a rewarder of them that diligently seek Him."
Believe God. You can't do a thing to save yourself. It's always depended on Him. Believe Him. He'll do the work. It's always been Him, and never been you or me at all.
