Everyone who goes on ahead and does not abide in the teaching of Christ, does not have God. Whoever abides in the teaching has both the Father and the Son. (2 John 9, ESV)
Jesus said, “If you abide in my word, you are truly my disciples” (Jno. 8:31). The apostle John reiterates this truth in today’s verse. We cannot go beyond what the teaching of Christ says without forfeiting fellowship with God. The reason is clear: God’s word is truth (Jno. 17:17). God does not sanction error, which is a lie against the truth (and God cannot lie, Titus 1:2). Jesus promises He and the Father will “make our home” with the person who loves Him and keeps His word (Jno. 14:23). John’s statement agrees with this. If you truly want to have a relationship with Jesus, then love Him, keep His word and do not go beyond it. Live by faith according to His truth, and Christ will live in you (Eph. 3:17).
