“...being diligent to preserve the unity of the Spirit in the bond of peace.” Eph 4:3
Unity among Christians is their natural state. Sure it is. Natural in the sense that is indeed God’s purpose for believers.
It is a permanent unity established by the Spirit of God. What you see and what you get... may not match that reality. But nonetheless, believers are bound together in the Person of Jesus Christ. Inseparably.
Where does that leave us?
Joined together - with many who in so many ways are different from us. Those who think differently, who respond differently, set different standards.
But we are joined together. That unity exists and if we give expression to the clear teaching of the Word of God, we will be humble gentle, patient and show forbearance to one another in love.
Read Ephesians 4:2-6. Easy? Not always. Maybe even not often. But God has both set unity in our union in Christ and given us the Spirit of God to enable us to live that reality.
It is the Holy Spirit Who produces fruit in our lives (Gal 5:22-23) and makes it possible for us to be peace keepers among all who know Jesus Christ as Savior.
In the light of your union with other believers in Christ, examine your heart to discover this truth again, in whatever way the Spirit of God indicates.
