'Obey' in the Bible

And He said to them, “Where is your faith [your confidence in Me]?” They were afraid and astonished, saying to one another, “Who then is this, that He commands even the winds and the sea, and they obey Him?”

Then a voice came out of the cloud, saying, “This is My beloved Son, My Chosen One; listen and obey and yield to Him!”

But He said, “On the contrary, blessed (happy, favored by God) are those who hear the word of God and continually observe it.”

And the Lord said, “If you have [confident, abiding] faith in God [even as small] as a mustard seed, you could say to this mulberry tree [which has very strong roots], ‘Be pulled up by the roots and be planted in the sea’; and [if the request was in agreement with the will of God] it would have obeyed you.
