Naturally you do have too much self confidence that YOU ... YOU have some the ability to live for Jesus.
There is only ONE person who has the ability to escape "mouth worship" and be absolute for the will of the Father -
Jesus. If you realize this after failure after failure after failure, you will draw your heart back from self confidence like pulling your hand back from a fire. Instinctively, you will realize that you need Christ and you need Christ moment by moment.
Step by step we need to enjoy His Spirit in our spirit. There is no other way to live overcomingly the Christian life. We have to utterly identify with Christ. For Christ alone is absolute for the will of the Father.
We have to "EAT" Him. That is masticate His word, take Him in, and set our mind on the mingled spirit. Are you born again ? We Christians are born of the Spirit in order to constantly drink of the Spirit. We brought our spiritual hunger to Jesus in order to "eat" the Lord Jesus all the time, everytime, everywhere - whether we're up or whether we're down.
" As the living Father has sent Me and I live because of the Father, so he who eats Me, he also shall live because of Me." (John 6:57)
In the local church life we learn to masticate His word, call on Him, breath Him, abide in Him moment by moment in order to "eat" Him. That is in order to live because of Him.
