But lift up your rod, and stretch out your hand over the sea and divide it. And the children of Israel shall go on dry ground through the midst of the sea."
Exodus 14:15-16 (NKJV)
Balance is very important. If you lose your balance you might fall and get hurt. If you are setting up stereo speaking you need to put them in the right place to balance the sound. In religious circles there has been a debate for many years about the sovereignty of God and the will of man. Some believe that because God is all powerful He can and will do whatever He wants to do, no matter what people might think or want to do for themselves. Other people believe that while God is all powerful it is up to us who believe in God to act on His Word in faith and if we don't then God will not do anything. This is how things often are, there are two extremes and in the middle is where you find the truth.
Everything is not just up to God, inspiration, and everything is not just left to the work of man, perspiration; there is a part God plays and a part we must play. While God is all powerful there are still some things that He wants us to do. We repeatedly see situations in the Bible like what happened with Moses by the Red Sea, God had already given Moses something to use in the situation. Moses had to stretch out the rod believing that God would do His part, but if Moses had never acted then God would have had nothing to work with. The rod that Moses had was not some magic wand but it was symbolic of the power of God that would and had worked in the life of Moses.
Another example is in John 9 where Jesus put clay on the eyes of the blind man. Jesus then told the man to go to the pool of Siloam and wash off the clay. When the man did so he could see. But what if Moses had not stretched out his rod, or the blind man had not gone to the pool? Then neither one would have received what God intended. In every situation God is ready to act but we must realize that it is not all up to the inspiration of God or the perspiration of man. God's power alone or our work alone will not bring the right results, we must find our part and act on God's Word to receive the results we desire.
