And only God knows the heart and the true spiritual place of the believer. I would encourage you to be convinced from the scriptures of your Biblical position. Then I would encourage you to respect and appreciate the position of every other brother and sister in Christ. Then come together as one to worship and do the work of our Lord. Jesus sent us not only to preach the Gospel and bring men and women to faith, but also to disciple those believers.
Discipline takes time.
It is investing your life in the life of others. It is often painful. But, it is also extremely rewarding. It is our intent not only to make converts but to raise up leaders who live according to the principles of God's Words. This is a transfer of living for self to living for Jesus.
