...The true nature of Christian love is a righteous principle which seeks the highest good of others. It is a powerful desire to promote their welfare. The exercise of love is to be in strict conformity to the revealed will of God. We must love in the truth. Love among the brethren is far more than an agreeable society where views are the same. It is loving them for what we see of Christ in them, loving them for Christ's sake.
The Lord Jesus Himself is our example. He was not only thoughtful, gentle, self-sacrificing and patient, but He also corrected His mother, used a whip in the Temple, Severely scolded His doubting disciples, and denounced hypocrites. True spiritual love is above all faithful to God and uncompromising towards all that is evil. We cannot declare, ‘Peace and Safety’ when in reality there is spiritual decay and ruin!
True spiritual love is very difficult to exercise because it is not our natural love. By nature we would rather love sentimentally and engender good feelings. Also many times true spiritual love is not received in love, but is hated as the Pharisees hated it. We must pray that God will fill us with His love and enable us to exercise it without dissimulation toward all. - A.W. Pink
