Is it unloving to deal with negative things and point out error? Paul tells us we are to let our love abound in knowledge and judgement. We are to approve by testing the things which differ (negative) and are more excellent. It is part of a process of walking free from offense until the day of Christ:
Php 1:9 And this I pray, that your love may abound yet more and more in knowledge and in all judgment;That ye may approve things that are excellent; that ye may be sincere and without offence till the day of Christ;
Once again, note that discernment and the coming day of Christ go hand in hand. When Paul speaks of being sincere and without offense, it means that we have truth in our inward parts, and we’ve also navigated through and been delivered from all of the untruths that have come and put stumbling blocks in the walk with our Lord. In the Bible, love and truth always go together. They cannot be separated.
James said that whoever helps a believer out of error saves a soul from death. It is sacrificial to risk our reputation, to risk being rejected, to risk being labelled as rebellious and divisive in order to help people see the true grace presented in the Gospel. It is contrary to every other message. It is not our fault that the church at large has deviated from the simple message of the Gospel and has developed into so many systems of error.
That being said, when we do address these things – we need to learn to speak the truth in love. Peter says that we should with meekness give an answer for the hope that lies within us. This is a skill that comes with maturity. Too often we can get into an argumentative mode and desire to be “right”. We need the Lord to train our heart to love the person we are speaking to and truly care about them.
