being diligent to preserve the unity of the Spirit in the bond of peace.Ephesians 4:3(NASB)
Paul knew that unity in the body of Christ can be threatened from without and destroyed from within. False doctrine and distorted scriptural truths can invade the Church and trivial dissensions and petty disputes can also be a destructive element that causes disunity. Christ earnestly prayed for unity (note- not uniformity) before He died: that they may be one..
Paul calls us all to be like-minded.. having unity in the spirit and the love of Christ in our hearts - being of one accord; encouraging the saints and demonstrating tender-compassion in humility of heart, towards one another. But mercy, truth and unity only comes when we have the grace of the Lord Jesus Christ, the love of God and the fellowship in the Spirit flowing through our inner beings - for it is only as we are yielded to the Holy Ghost, that He is enabled to conform us, into the likeness of Christ.
We have the mind of Christ - to think as He did; to speak as He did; to live as He did and to behave as He did. And so individually and collectively we have the means to walk and live and pray in spirit and truth.
In his letter to the Philippians Paul gives this vital challenge to all believers - IF we have received any consolation in Christ; if therefore we have any comfort of love; if therefore we have any fellowship of the Holy Spirit and if therefore we have any bowels and mercies in Christ, then we are to demonstrate this in our lives by being of one same mind
If we, as children of God, have received His goodness and grace, comfort and hope, we are to maintain the same goodness, grace, comfort and love and be diligent to preserve the unity of the Spirit in the body of peace.
The challenge to all believers is to faithfully and committedly develop a Christlike character, demonstrating the same love that He displayed. We are to be united in spirit and fervent in love - looking to Jesus, the author and perfecter of our faith, Who for the joy that was set before Him endured the cross.
Heavenly Father I pray that I may show forth the grace of Christ, the love of the Father and the fellowship of the Holy Spirit - in thought word and deed, towards all who are the called according to Your purpose, so that in unity of spirit we may honour Your name, through our earthly witness, in Jesus name I pray, AMEN.
