God Smiles When We Obey Him Wholeheartedly:

Saving the animal population from a worldwide flood required great attention to logistics and details. Everything had to be done just as God prescribe it. God didn’t say “Build any old boat you’d like, Noah” He gave very detailed instructions as to the size, shape, and materials of the ark as well as the different numbers of animals to be brought on board. The Bible tells us Noah’s response: “so Noah did everything as God had commanded him.” notice that Noah obeyed completely (no instruction was overlooked), and he obeyed exactly the way and time God wanted it done. That is wholeheartedness. It is no wonder God smiled on him.
If God asked you to build a giant boat, don’t you think you might have a few questions or reservations? Noah didn’t. He obeyed God wholeheartedly. Partial obedience is disobedience, and wholehearted obedience is done joyfully with enthusiasm. The Bible says “Obey him gladly”. This is the attitude of David. “Just tell me what to do and I will do it, Lord. As long as I live I will wholeheartedly obey”.
When James was speaking to Christians, he said, “We please God by what we do and not only what we believe.” God’s word is clear that you can’t earn your salvation. It comes by grace, not your effort. But as child of God you can bring pleasure to your heavenly Father through obedience. Any act of obedience is also an act of worship. Why is obedience so pleasing to God? Because it proves you really love him. Jesus said, “If you love me, you will keep my commandments”.
