To say that doctrine matters more than feelings is not to say that the feelings of others are invalid or that they shouldn't be considered at all when communicating truth. Feelings are certainly to be considered when teaching or confronting someone, particularly when it comes to more difficult and even unpleasant biblical truth. Of course, the truth is to always be spoken in love; and, in fact, it is this love for others which causes us to be sensitive to how they might receive our words. That said, our consideration must only go so far. Biblical truth is not to be compromised or withheld for fear of offending someone or in order to prevent making them uncomfortable. We shouldn't forget the reality that God has feelings. And to believe that doctrine matters more than feelings, is to believe that God's approval matters far more than man's.
In the name of love, it is tempting to cater more to someone's temporal feelings than their eternal souls. But, Christians must fear the discomfort of man more than the displeasure of God. Convinced that nice is a fruit of the Spirit, many in the Church refuse to teach or embrace many of the Bible's more difficult doctrines, such as sovereign election, hell, sin and repentance, judgment, holiness, discipline, lordship, evangelism, etc. The result is an over-emphasis on "the love of God." And this is not to say the agape love (God-kind of, self-sacrificing) found in Scripture, but a version of love reduced to that which is only positive, encouraging, and feels loving at the moment. To redefine love in this way results in the exclusion of God’s other attributes. This is the problem, because the reality is that God is all of His attributes fully and simultaneously. And, it is this incomplete understanding of God which allows for the feelings of others to be considered above the feelings of God.
