Read: Matthew 6:9-13
And lead us not into temptation, but deliver us from evil. (Matthew 6:13 ESV)
The final passage of the Lord's Prayer, found in the Sermon on the Mount, is a clarion call from Christ for God to aid His people in our natural struggles with sin and evil. It's a position we truly do need God's help with. As fallen people we regularly put ourselves in harm's way. We repeatedly place ourselves in situations where sin and temptation are easily accessible. We need God's help in changing our hearts, minds, and motives.
This point hit home for me a couple of days ago as I was feeding my son breakfast. I had him strapped into his highchair and he kept gesturing for things around the room that he wanted. They were all things he was normally allowed to have, but they were not his breakfast. Someone had left these items within sight. They were tempting him. He desired them. In order for me to get him to eat his breakfast I had to remove the distractions. Once they were all put away he went on eating breakfast, the other stuff no longer mattered.
It's not God's duty to keep us from temptation. Often I believe we bring it on ourselves. I do however believe that He will help us rid our lives of things that distract us from Him if we ask Him to. And I believe He is often urging us to want His help in doing so. And I firmly believe that God is never the source of temptation for His children.
