“The presence of sin in the believer involves conflict in his heart and life. If there is remaining, indwelling sin, there must be the conflict which Paul describes 7:14ff. It is futile to argue that this conflict is not normal. If there is still sin to any degree in one who is indwelt by the Holy Spirit, then there is tension, yes, contradiction, within the heart of that person. Indeed, the more sanctified the person is, the more conformed he is to the image of his Savior, the more he must recoil against every lack of conformity to the holiness of God. The deeper his apprehension of the majesty of God, the more persistent his yearning for the attainment of the prize of the high calling in Christ Jesus, the more conscious will he be of the gravity of the sin which remains and the more poignant will be his detestation of it.”
