Now I, Paul, myself am pleading with you by the meekness and gentleness of Christ—who in presence am lowly among you, but being absent am bold toward you. 2 But I beg you that when I am present I may not be bold with that confidence by which I intend to be bold against some, who think of us as if we walked according to the flesh. 3 For though we walk in the flesh, we do not war according to the flesh. 4 For the weapons of our warfare are not carnal but mighty in God for pulling down strongholds, 5 casting down arguments and every high thing that exalts itself against the knowledge of God, bringing every thought into captivity to the obedience of Christ, 6 and being ready to punish all disobedience when your obedience is fulfilled. —2 Corinthians 10:1-6.
Paul says that if he has to come to deal with the sin of the church face to face, he will be as bold in his presence as he is in his letters. Dealing with sin is part of spiritual warfare to be fought with God’s help. It is not a physical war. The aim of this war is to pull down everything that opposes obedience to Christ in the life of the believer and to turn disobedience into obedience. [The Bible Panorama.]
