At the age of 95, having walked with God for over 65 years, the apostle John decided to write a letter - inspired by the Holy Spirit. The theme of his letter was 'fellowship' (1 Jn. 1:3). Having seen churches and leaders who had left their first love (Rev. 2:4) and who now had a name that they were alive (with all their varied Christian activities) but who were in fact dead in God's sight (Rev. 3:1), John certainly saw that the great need was to lead Christians into the joy of fellowship with the Father and His Son Jesus Christ, inside the rent veil.
There may be joy found in several fields of activity. Some find it in sport, some in music, some in their profession, and some even in Christian work. But the purest joy in the universe is to be found only in fellowship with the Father (1 Jn. 1:4).
The psalmist says, "In Thy presence is fullness of joy" (Psa. 16:11). This was the "joy set before Him" that made Jesus willing to endure the cross daily (Heb. 12:2). The fellowship with the Father was Jesus' most prized possession. He did not value anything else in the universe in comparison with that. This fellowship was what Jesus knew would be broken on Calvary, when for three hours He would have to endure the agonies of an eternal hell for lost humanity (Matt. 27:45). Then the Father would have to forsake Him, and the fellowship that He enjoyed with the Father from all eternity would be broken for three hours. He dreaded that break of fellowship so greatly that He sweated great drops of blood in Gethsemane. The cup that He prayed to be removed from Him was just this: A break of fellowship with His Father.
If only we could see this and be gripped by it! How lightly we speak and sing about following Jesus! To follow Jesus means to value fellowship with the Father like He did. Sin would then become exceedingly sinful to us, for it breaks our fellowship with the Father. An unloving attitude towards another human being would not even be tolerated, for it would break our fellowship with the Father.
May the Lord give us revelation so that we see clearly that true Christianity is nothing less than a life of unbroken fellowship with a loving Father in heaven.
