John 7:17 If any man will do his will, he shall know of the doctrine, whether it be of God, or whether I speak of myself.
Faith and belief are of the heart and invisible to men. Obedience is seen in our outward conduct, and it may be observed by men. When a Christian obeys God, he gives the only possible evidence that in his heart he believes God. Obedience is not some sort of depressing, long‑faced act of endurance. There is joy and peace in doing what is right.
We live in a generation who are always wanting reasons, always wanting alternatives or options to choose from, always wanting to know what are the benefits in it for me. If the reasons are reasonable, if the options are acceptable, if the benefits are appealing ‑‑ then we’ll obey. But remember, these two thoughts:
1) God seldom gives us all the reasons for His commands to obey, and
2) God is smarter than we are.
Sometimes we have to obey in order to understand. Jesus said, If any man will do his will, he shall know of the doctrine, whether it be of God, or whether I speak of myself John 7:17.” I’m sure Noah did not fully understand what was going to happen when God told him to obey and build an ark but after the Flood subsided I’m sure he was glad that he did obey (Genesis 6:22).
