What makes fellowship so important is that man was created to enjoy fellowship with his God, and undoubtedly did so in his unfallen state in Eden. But the entrance of sin changed all that, and the spiritual death which ensued from Adam’s disobedience made such communion impossible. Now, on the basis of the abounding grace of God, by means of the reconciling work of Christ on the cross and the regenerating work of the Spirit, believers become new creatures in Christ Jesus (2 Cor. 5:17), with the spiritual capacity for fellowship with their God. … Thus the believer in Christ has been brought into fellowship with the triune God. And this becomes the basis for our fellowship with all of like precious faith.
