Psalms 46:10 Be still, and know that I am God! I will be praised among the nations, I will be praised in the earth.
In one passage in John, Mary and Martha come running to Jesus, asking Him to heal Lazarus, who was critically ill. Since Lazarus was a good friend of Jesus, I'm sure they were expecting that Jesus would come immediately to his aid. The scripture says, however, that Jesus stayed two more days in the place where He was. It was in those two days that Lazarus died.
It's so hard to understand why it is that God waits to do the things we ask of Him. It's good for us to remember, though, that He has His purposes for waiting. God was about to teach everyone involved a much deeper lesson here. As Jesus raised Lazarus from the dead, He made sure they all understood that He is the resurrection and the life for all who believe.
God has His perfect timing for everything under heaven. You may be waiting for God to intervene in some area of your life. You may have been begging and pleading with God for years on that particular thing. But we can relax and know that God's timing is perfect. We never know what God is doing behind the scenes, in order that our joy would be made full. Remember that He knows best what would bless us most and He is working all things for those of us who love Him and are called according to His purposes.
Relax. God is in control. He has greater things for you than what you could ask or think!
