Regain faith, willfully sin, backslide, REPEAT REPEAT REPEAT.
How do I end this vicious cycle?
I am getting to the point where I don't even want to try because I know the cycle will repeat (or so my mind[or satan] tells me).
So how am I to overcome this? Maybe I'm not saved to begin with? Any counseling/biblical advice?
This may sound strange, but I don't believe you sin willfully and the bible says you don't. Sin is a state of depravity. You can't will your way out. That's why Christ died for our sins. Thats why he said forgive them for they know not what they do.
Believing you must try to stop your sin only makes you beat yourself up with guilt when you fail. Take heart, for Jesus said, Blessed are those who hunger for righteousness, that's you:help
How to Get It? First, know love is a man's righteousness. For you to have God's righteousness, you must acknowledge it comes through Him. Your standard of righteousness must be the Christ that would die for others. You must bear your own cross. Only God's pure love can accomplish this. It's because we don't give God His proper regard that sin exists.
Don't hold others responsible for their tresspasses. When you see bad things happen in the world don't blame people, think to yourself, they know not what they do. Think about how Christ suffered for us and understand why, even because he knew we couldn't help it. Stop believing anyone else can help their sin. Then you won't be in a state of hypocrisy and your conviction steady. Forgive all people who have ever hurt you and forgive those who are yet going to. Understanding no one can help their sin and being convinced of that, will remove the guilt. Change your mindset.
Now make some step in the right direction. Do something good in the world, let's start small. Give some little kid $5. If you truly are hungry for righteousness you will do your charity gladly, looking forward to doing it. As you walk away thinking about the joy you brought that little kid, now this is important, immediately thank God for your love, do not take credit for it. If you do you missed the point. God is our righteousness. If you take credit for it, you can't have His righteousness. You steal His Glory, remember Jesus said, Thy will be done, not mine. Treasure your Love that He is, The more you treasure it, the more you walk in it. You can't treasure it if you think it's you doing it.
All sin is carnal, your flesh only understands pain and pleasure. It's not about trying not to sin. It's about using love to sacrifice yourself for others. To walk in the Spirit is to put the interests of others ahead of your own. Love is the power that does this, if you only believe in Him and not in yourself. Use moderation in everything that is a potential vice. The Holy Spirit will guide you and the more you realize it is Him living in you, the more you will know Him and the more you will love Him. He will cleanse you of sin the more your faith grows. He loves honesty and humility, and this is all He asks from you. Believe me, if you're honest with Him, He'll straighten you out, and He'll do it with the sweetest gentleness. No matter what other people tell you, don't listen if they say It's up to you to conquer your sin. You won't get the true Spirit from the cross if it makes you feel guilty to look at, or think of, the Christ crucified. Therefore I leave you with strong scripture to force your resolve. When you doubt, in other words when the devil attacks, think of this, Romans 7:18-20
For I know that in me, that is in my flesh, dwells nothing good; For to will to do good is present in me, but how to perform that which is good I find not. For the good I will to do, I don't do. But the evil I wish I wouldn't do, that I do. Now If I do That which I wish I wouldn't do, it is no more I that do it, but sin that dwells in me.
Romans 7:24,25
O wretched man that I am, who shall deliver me from the body of this death. I thank God through Jesus Christ our Lord.
