Completely true. That is how God is indeed. When He releases His blessings upon you, you will feel His smiling face because it gives Him pleasure to bless those who love and obey Him without any strings attached.
Faith in God is obedience to His will and dictates, When He gives you an instruction to follow, your faith in Him will spur you to obey Him and please Him, you can't obey what or who you don't believe or have faith in...
I agree with this teaching absolutely. See 1 Thessalonians 4:1 "As for other matters, brothers and sisters, we instructed you how to live in order to please God, as in fact you are living. Now we ask and urge you in the Lord Jesus to do this more and more".
