We are in Christ, we should strive to keep the unity of the Spirit but personally, as followers of Christ, we should live different to the world, living Christlike lives of honesty and kindness.. because that’s what Jesus did for us!
Over chapters 4 to 6, Paul challenges his readers to ‘live a life worthy of the calling they have received.’ That begins with a call to maintain, with great humility, the unity God has wrought by the work of the Spirit and to all play our part in the building up of God’s people. The aim is spiritual maturity and godliness of character.
Through faith in Jesus Christ we are not only brought into God’s family and are united with Jesus, but that shared faith also unites us to other faithful believers, whatever their background!
