Backsliding?

Why do christians backslide? I just backslided today for the first time in about 2 weeks i think. I feel terrible about it and i know i just backslided. I think the reason I did was because I feel like I cant live up to Gods high Standards. And I felt for a while that I was very close to god and jesus and still do, I mean I know I am saved but I did the exact same thing i did before i was saved. But the difference is I didnt get any pleasure from it. So i know I am saved but i feel like im not forgiven. And I also felt during that time of being very close to god that I had to retreat from the world leaving old friends and other unbelievers behind to keep from reverting back to my old ways. Someone please help me on this!

I think you're learning about the need for grace, God's unmerited favor. God loves us just as much when we fail as when we have victory. In fact, He sees through victories won by will power and such, and knows that we will need to come to the Cross in order to secure permanent victory. I've had so many ups and downs that all I want now is God's grace to drive my walk. As Paul says in Phillipians 3, we should place no confidence in the flesh.

He also assures us that because we are under grace, sin will not have dominion over us. Keep abiding in Christ's love, and don't focus overly on your own performance. (Of course, don't go out and purposefully sin!) It is good for the heart to be established by grace - Heb. 13. If you need assurance, try reading Romans 8. And never doubt His forgiveness and love.
