Christian life is a life of friendship with God, ‘I have called you friends’ (John 15, 5). More, we are called to share the divine life itself in fellowship with Christ and as members of God's family; ‘God is faithful, by whom you are called unto the fellowship of his Son, Jesus Christ our Lord’ (1 Cor. 1, 9). He is our elder brother, ‘the firstborn among many brethren’ (Rom. 8, 29); we receive the spirit of adoption of sons, and are joint heirs with Christ (Rom. 8, 15-7).
