He [Jesus] said to Simon, “Put out into deep water, and let down the nets for a catch.”
Simon answered, “Master, we’ve worked hard all night and haven’t caught anything. But because you say so, I will let down the nets.”
When they had done so, they caught such a large number of fish that their nets began to break. So they signaled their partners in the other boat to come and help them, and they came and filled both boats so full that they began to sink.
When Simon Peter saw this, he fell at Jesus’ knees and said, “Go away from me, Lord; I am a sinful man!” For he and all his companions were astonished at the catch of fish they had taken
Luke 5:4-9
Has God told you to do something that seems to go against obvious indicators for success, or maybe you just don't see how it could ever work?
When God challenges us to trust His word to undertake something, even when it fails a feasibility assessment from a human perspective, He is allowing us to discover more and more of His personality and power. Peter had only recently met Jesus when He had the experience described above. This show of Christ's wisdom and power to pull off the most successful fishing expedition ever, without hardly trying, brought a holy fear upon Peter. He realized he was in the presence of no ordinary man, and saw himself in stark contrast, as he really was. In the same way, God wants us to know Him. In continually acting upon His word we will become increasingly confident that His plan always works. Peter had the opportunity to see an immediate reward in taking Jesus at His word despite the 'facts' that surrounded his situation. In our own lives we may have to wait a little while depending on the situation, but whatever God asks us to do is always for our own good ultimately. As Christians we soon realize that the Lord will continually require us to trust and obey Him; and that our peace, joy, and success depends upon it.
Just like Peter dared to be in the Bible snippet above, let's make a decision to become people who always say to God "because You say so, I will."
“Whatever He says to you, do it.”
~ John 2:5
