The song teaches that we should obey and trust God when He calls us into His Kingdom or unto a task. Many are the times we despise His intentions for us but as a loving Father, He respects our choices. Obedience to God in all things, even the mundane, is a great way to show our love and respect for him. He knows everything we are going through at this very moment and everything we will go through in the future. Trusting Him goes beyond feelings. Rather, it means that we trust in both His character and His promises. We believe that He is good and that He loves us. We believe that He will fulfill all the promises He Has made to us. Rather than trusting in our own senses and ideas, we believe in God and His word. The song addresses such issues. JUST DO IT!
