God Works in the Simple Things
John 14:7 "If ye had known me, ye should have known my Father also: and from henceforth ye know him, and have seen him."
Knowing Jesus is knowing the Father. This is not only because Jesus did exactly what He saw His Father do, but Jesus was God in the flesh.
The disciples didn't realize that seeing Jesus was seeing God. They were expecting something more. Many times we miss seeing God work in our lives and circumstances because we are looking for something stupendous. Although it is true that God is totally awesome, He doesn't usually choose to manifest Himself in that way.
God spoke to Elijah not in the fire, wind, or an earthquake, but in a still, small voice. Jesus didn't come to this earth in a grand way by man's standards, but was born to poor parents in a stable. Isaiah 53:2 says that Jesus had no form nor beauty that would make us think that He was anything more than a mere man.
Paul reveals in 1 Corinthians 1:27-29, that God chooses to do things this way so that no flesh will glory in His presence. The Lord wants us to focus on Him through faith and not concentrate on the physical things He uses. In the Old Testament when the Lord did use visible instruments to release His power, the Israelites made idols out of those things.
Just as the disciples saw Jesus but didn't realize that what they saw was God, likewise, God is infinitely involved in our everyday lives, but we miss Him because we are blinded by our carnal minds. The primary reason that God chooses to use those who are nothing by the world's standards is so that no one else will take the credit for the great things that are accomplished.
