We have just posted a new sermon called Create in Me a Clean Heart: A Serious Call to Sexual Purity. Here’s an excerpt:
Purity is worth it because the pure in heart see God. They know him deeply, personally, intimately. They have an inner peace that others do not have. They see God and know the comfort of his presence and the joy of his blessing. Purity will cost you a great deal, but it's one investment you will never regret.
I am keenly aware that some people reading my words feel totally defeated. Perhaps you have already blown it so badly that you feel there is no hope for you. Perhaps you have not been faithful to your husband or wife, and you wonder, "What's the use?" Maybe you were promiscuous in your younger days or possibly before you came to Christ. It may be that you have burning memories of recent moral failure. Perhaps you have fallen victim this very week to Internet pornography. Is there any hope for you or must you remained stained and soiled for life? There are two answers to that question. The first is that sin always brings negative consequences. Nothing I can say will change that fact. And some sins bring large consequences that last for a lifetime.
However, I have some better news for you. Jesus has something he wants to say to you. "Rise and walk" is the Lord's message to every broken sinner. "Go and sin no more."
Many Christians waste a lot of time trying to have a better past. It is what it is. You can't change the past, but you can do something about the future. By God's grace you can be clean and pure from this day forward. You don't have to live in guilt or fear or shame any longer. Rise and walk, child of God. Get up out of the muck and mire of shameful defeat. In the name of Jesus, rise and walk!
