4:1-6 Nothing is pressed more earnestly in the Scriptures, than to walk as becomes those called to Christ's kingdom and glory. By lowliness, understand humility, which is opposed to pride. By meekness, that excellent disposition of soul, which makes men unwilling to provoke, and not easily to be provoked or offended. We find much in ourselves for which we can hardly forgive ourselves; therefore we must not be surprised if we find in others that which we think it hard to forgive. There is one Christ in whom all believers hope, and one heaven they are all hoping for; therefore they should be of one heart. They had all one faith, as to its object, Author, nature, and power. They all believed the same as to the great truths of religion; they had all been admitted into the church by one baptism, with water, in the name of the Father, and of the Son, and of the Holy Ghost, as the sign of regeneration. In all believers God the Father dwells, as in his holy temple, by his Spirit and special grace.
2, 3. lowliness—In classic Greek, the meaning is meanness of spirit: the Gospel has elevated the word to express a Christian grace, namely, the esteeming of ourselves small, inasmuch as we are so; the thinking truly, and because truly, therefore lowlily, of ourselves [Trench].
meekness—that spirit in which we accept God's dealings with us without disputing and resisting; and also the accepting patiently of the injuries done us by men, out of the thought that they are permitted by God for the chastening and purifying of His people (2Sa 16:11; compare Ga 6:1; 2Ti 2:25; Tit 3:2). It is only the lowly, humble heart that is also meek (Col 3:12). As "lowliness and meekness" answer to "forbearing one another in love" (compare "love," Eph 4:15, 16), so "long-suffering" answers to (Eph 4:4) "endeavoring (Greek, 'earnestly' or 'zealously giving diligence') to keep (maintain) the unity of the Spirit (the unity between men of different tempers, which flows from the presence of the Spirit, who is Himself 'one,' Eph 4:4) in (united in) the bond of peace" (the "bond" by which "peace" is maintained, namely, "love," Col 3:14, 15 [Bengel]; or, "peace" itself is the "bond" meant, uniting the members of the Church [Alford]).
