Faith, the ability to, or act of believing God -
is what pleases God.
"Without faith it is impossible to please Him,
for he who comes to God must believe that
He is and that He is a rewarder of those who
diligently seek Him"
Hebrews 11:6
Without faith, it is not just hard to please God,
it is absolutely impossible.That is because, if
something is not of faith, it is not of God.
"Whatever is not of faith is sin"
Romans 14:23
When we have faith and put it into action,
which is what it means to believe, God is greatly
pleased.
Faith is believing God and that honors Him.
