Welcome to the site! I hope you enjoy it.
One thing I would like to share with you that God revealed to me that attributed to my healing is that NOBODY has the power that you have attributed to them. Here it is: Do not give power to anyone, power that God did not give them. Satan wants you to empower everyone over yourself. He wants you to think that they have a special power, but they don't have it. So empower nobody. Since God did not give them this type of power then they don't have it.
Secondly, you must come to see that you must empower yourself with the legitimate power God gave you. Do you know that we are seated with Christ in the Heavenly places right now according to Ephesians? That means that we are in a position of authority. Jesus has everything under his feet and he is seated on the right hand side of the Father in Heaven. And you are seated with Him through your faith in Him. To know your identity in Christ is to know your power over your circumstances. Your problem is under your feet--not because you have power, but because the one you are seated with has all power. Jesus said "Then you will know the truth, and that truth that you know will set you free." When you know the truth of your new identity in Christ, you will be set free from you anxiety just as I have. Go over my earlier posts and you'll see how bad my anxiety was.
Thirdly, by virtue of our new identity in Christ, we have access to God's power of grace. Grace is not some idle term to throw around that means nothing. Grace is the Christians power that God gives to every believer in Jesus. Grace is God doing for you what you are unable to do for yourself. But it takes emptying ourselves of ourselves and our own efforts to access God's grace of Him doing it for us. It is stepping out on His power. It is first realizing and confessing our own inefficiency of our own fleshly strength and putting on Jesus' strength. So what GOd will do when we step out like this is He will take over. And you will see power that you didn't have before.
Before going out on grace confess your sins. Repent and ask God to let his power of Grace keep you from sinning again. He will do that for you. Grace is our power for everything, including overcoming a sin we couldn't get rid of by our own effort and will power. And then grace will give you the power to overcome your anxiety.
