Freewill and God's will

Allow God to keep you from sin.  We can't hardly blame God for not protecting us from sin when we are actively seeking after it or doing nothing to avoid it. 
In the morning, awaken with the first thought of thankfulness for God's mercy and grace toward us.  Thank him for not dealing with you as your sin deserves.  Think through your day and how you can avoid or successfully work through potentially sinful situations.  Then pray for God's help to keep you from sin.
Far too often we don't want to do the work ourselves.  We only want God to wave a magic wand.  It doesn't work that way.  As men created in the image of God, we have responsibilities and freedom to live.  Be responsible enough to handle that freedom.  The very state of your soul depends upon it.
