37. Christians exhibit perfect love when, in addition to the love they manifest toward all men, they are themselves united by a peculiar bond of Christian affection. The term "tenderly affectioned" expresses the love parents have for children, and brothers for each other. Paul would say: "Christians are not simply to manifest a spirit of mutual love, but they are to conduct themselves toward one another in a tender, parental and brotherly way." Thus Paul boasts of doing in the case of the people of Thessalonica. 1 Thes 1, 11. Isaiah declares (ch. 66, 13) that God will so comfort the apostles: "As one whom his mother comforteth, so will I comfort you." And Peter says (1 Pet 3, 8): "Loving as brethren, tenderhearted, humbleminded." The nature of the brotherly love we owe our neighbors is illustrated in the love of an affectionate mother for her child. Such love Christ has shown, and still shows, toward us. He sustains us, frail, corrupt, sinful beings that we are. So imperfect are we, we seem not Christians at all. But the love of Christ makes us his, regardless of our imperfections. "In honor preferring one another." 38. Christ's love and friendship for ourselves should lead us to esteem one another precious. We should be dear to one another for the sake of the Christ within us. We may not reject any because of his imperfections. We must remember the Lord dwells in the weak vessel also, and honors him with his presence. If Christ regards him worthy of kindness and affection, and extends to him the same privilege in himself that we enjoy, we should bow before that weak one, honoring him as the living temple of our Lord, the seat of his presence. What matters to us the insignificance of the seat the Lord chooses? If it is not too humble to be honored with his presence, why should we his servants not honor it? "In diligence not slothful." 39. "Diligence" here implies every form of righteous work and business that occupies us. Paul requires us to be diligent, skillful and active. We are not to proceed as do they who undertake one thing today, and tomorrow another, confining themselves to nothing and soon growing weary and indolent. For instance, some readily and very zealously engage in a good work, such as praying, reading, fasting, giving, serving, disciplining the body. But after two or three attempts they become indolent and fail to accomplish the undertaking. Their ardor subsides with the gratification of their curiosity. Such people become unstable and weak. So Paul enjoins to be "Fervent in spirit."
