To first get the proper perspective, we have to start with the attitude that we are in bondage to our sin. In the fact that Jesus came to save us from our sin, we can see that we are unable of being freed from sin on our own. I've always been down on myself because I can never seem to stop doing the sins I'm trapped in. I am saved of course, and am forgiven of my sins, but there are areas of my life that I struggle with. For me the primary area is the sin of gluttony. I've struggled for years with having an ungodly perspective of food. It's been my idol. I've tried for years to quit being gluttonous to no avail.
I've learned through working through the Lord's Table Bible study that I've never been able to break those chains, because that's God's work. How freeing! Yes, I have to have a repentant heart, but I can not just turn 180 and stay that way without the help of God. I had to realize that it takes a humble heart for God to be able to work. I have to have the attitude that I'm unable to do anything outside of His power. I have to rely on Him completely to free me of my bondage to sin.
This requires that I walk in the Spirit. This means that I have the eyes of my heart opened, and walk with a humble, repentant heart. It is impossible to walk in the spirit if you are living in sin. Living in sin doesn't mean we are not forgiven, or not saved, it means that we are allowing Satan to enslave us, and not having a repentant heart in any given area. When we are walking in the Spirit, we allow God to talk to us whenever he needs to and we need to be obedient. This is how He does His work!
When we are walking in the Spirit, we will be able to hear His voice. He will reveal to us areas that need to be changed, and will root out any weeds of sin in our lives. We have to be listening, open hearted, and ready to obey. He may reveal that you need to forgive someone, or he may reveal an area of sin that you have no clue that was there. He may have something very drastic to do in your life. You have to walk in the Spirit with a humble, repentant heart, ready to obey what God has called you to do.
If the church today would walk ready to allow God to do the work, instead of trying to do the work in their own power, or world would be a totally different place!
