You, God, are my God, earnestly I seek you; I thirst for you, my whole being longs for you, in a dry and parched land where there is no water. I have seen you in the sanctuary and beheld your power and your glory. Because your love is better than life, my lips will glorify you. I will praise you as long as I live, and in your name I will lift up my hands. I will be fully satisfied as with the richest of foods; with singing lips my mouth will praise you.(PSALM 63:1-5)I'm not saying you will not be tempted to return to your old ways. We are sinful humans, after all. But there is always hope. Hope in Christ Jesus. The blessing that you are never alone in the struggles. That He will help you. The first step, is admitting you have a problem and letting Him in to the deepest recesses of your soul to the holes you don't show anyone.
If you think you are standing strong, be careful not to fall. The temptations in your life are no different from what others experience. And God is faithful. He will not allow the temptation to be more than you can stand. When you are tempted, he will show you a way out so that you can endure.(1 CORINTHIANS 10:12-13)
