UNITY IN LOVE
Ephesians 4:1-7I therefore, the prisoner of the Lord, beseech you that ye walk worthy of the vocation wherewith ye are called, with all lowliness and meekness, with longsuffering, forbearing one another in love; endeavouring to keep the unity of the Spirit in the bond of peace. There is one body, and one Spirit, even as ye are called in one hope of your calling; one Lord, one faith, one baptism, one God and Father of all, who is above all, and through all, and in you all. But unto every one of us is given grace according to the measure of the gift of Christ.
UNITY IN LEARNINGAnd He gave some, apostles; and some, prophets; and some, evangelists; and some, pastors and teachers; for the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ till we all come in the unity of the faith, and of the knowledge of the Son of God, unto a perfect man, unto the measure of the stature of the fulness of Christ: that we henceforth be no more children, tossed to and fro, and carried about with every wind of doctrine, by the sleight of men, and cunning craftiness, whereby they lie in wait to deceive; but speaking the truth in love, may grow up into Him in all things, which is the head, even Christ: from whom the whole body fitly joined together and compacted by that which every joint supplieth, according to the effectual working in the measure of every part, maketh increase of the body unto the edifying of itself in love.
UNITY IN LIVING
Ephesians 4:17-32 This I say therefore, and testify in the Lord, that ye henceforth walk not as other Gentiles walk....
putting away lying, speak every man truth with his neighbour.... Be ye angry, and sin not: let not the sun go down upon your wrath...steal no more: but...labour...to give to him that needeth....Let no corrupt communication proceed out of your mouth....Let all bitterness, and wrath, and anger, and clamour, and evil speaking, be put away from you, with all malice: and be ye kind one to another, tenderhearted, forgiving one another, even as God for Christ's sake hath forgiven you.
Jesus thought unity was absolutely essential for winning the lost (Jn. 17:21-23)!
