Hebrews 3:4 “And Moses verily was faithful in all his house, as a servant, for a testimony of those things which were to be spoken after; 6 But Christ as a son over his own house; whose house are we, if we hold fast the confidence and the rejoicing of the hope firm unto the end.”
Care must be taken to not confuse this passage with the Eternal State of the Children of God; for our Lord plainly declared, “of all which” God The Father “hath given me I should lose nothing, but should raise it up again at the last day” (John 6:39); that is, “the elect of God” (Colossians 3:12) are Eternally Secure and were made righteously (2 Corinthians 5:21) fit for Eternal Heaven when Jesus Christ declared on the Cross, “It is finished” (John 19:30). This passage has to do with our part and behavior in the “house” of God, the Church-Kingdom of Jesus Christ our Lord, “the house of God, which is the church of the living God, the pillar and ground of the truth” (I Timothy 3:15). To have part in our Lord’s “house” we must do two things, “hold fast the confidence and” “hold fast … the rejoicing of the hope firm unto the end”. To “hold fast” is to tenaciously and boldly hold our ground, much like a “good soldier” (II Timothy 2:3) will “hold fast” his assigned ground no matter how severe the battle becomes. To “hold fast the confidence” is to not waver in declaring and obeying the truth of Jesus Christ and His great Sacrifice on our behalf; that is, we “should earnestly contend for the faith which was once delivered unto the saints” (Jude 1:3) and “continue in the faith grounded and settled, and be not moved away from the hope of the gospel” (Colossians 1:23). To “hold fast … the rejoicing of the hope firm unto the end”; is to “hold fast” in joyfully worshiping our Lord, worshipfully “rejoicing in” “the hope which is laid up for you in heaven, whereof ye heard before in the word of the truth of the gospel” (Colossians 1:5), and to spend our time on this earth joyfully “Looking for that blessed hope, and the glorious appearing of the great God and our Saviour Jesus Christ” (Titus 2:13). Men destroy their part in our Lord’s “house” on this earth, when they fail to “hold fast” these things to “the end” of their lives. We are to “hold fast” these things whether our lives be short or long and whether our lives be pleasant or troubled. There is a peril that lurks in every generation; men begin to replace Biblical truth with human intellect and pride, alter the Word of God to fit some carnal bent, seek carnal gain and glory over humble sincerity, and bring unbiblical doctrines and practices into our Lord’s Church-Kingdom. Let it not be said of our generation that we were unfaithful to the Doctrine of Christ and His Church-Kingdom but that we held “fast” the Bible’s doctrinal ground and the faithful allegiance and obedience to our Lord.
