Since God is “a God of truth” (Deuteronomy 32:4), it makes sense that the words proceeding forth from His mouth would reflect and demonstrate the same nature as their author. According to the scriptures, this is exactly what has happened. The psalmist said, “thy law is the truth” (Psalm 119:142) “and all thy commandments are truth” (Psalm 119:151). The Lord Jesus confirmed this when He said, “Sanctify them through thy truth: thy word is truth” (John 17:17). If God is worthy of praise for being a God of truth, it only makes sense that His truth would also be worthy of man’s praise (Psalm 71:22). God, knowing this truth, magnified His word above all His name (Psalm 138:2).
The Lord wants His children to have joy and that without limitations. He wants Christians to experience the fulness of joy that only comes from right relationships. This fulness only exists in the lives of believers as certain conditions are met. The right relationship involves fellowship with God which in turn evolves into the right kind of fellowship with other believers. According to today's passage, the words of the Lord Jesus bring fulness of joy to the saint of God. Additionally, answered prayer offers fulness of joy (John 16:24). In addition to our fellowship with the Lord, the Bible suggests that fellowship with other believers also yields fulness of joy (2 John 1:12). Every astute Bible student recognizes that these two fellowships are inextricably linked (1 John 1:3). No dedicated Christian can experience true fellowship with other dedicated believers without first having the right kind of fellowship with God Almighty.
