Have you ever come across those you felt to be unteachable? Often this occurs when the one you are teaching are not in agreement with the fundamentals of Christianity. In fact, many already in the church are not in full agreement with some of these fundamentals. Before anyone can be taught the gospel and doctrine of Christ they must accept these basic truths:
All Scripture Came From God The Father
Until one accepts God as the ONLY author of the bible, then there is no way to teach them about the Lord and his church. Paul made it very clear on this subject when he wrote, “All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness, that the man of God may be complete, thoroughly equipped for every good work” (2 Tim 3:16-17). The fact of the bible’s origin is this, that it was written by inspired men. They were not inspired of man but of God. This is true for the fathers and prophets of old (1 Pet 1:21). This is true for the apostles of Jesus christ (Jn 14:26 cf; Jn 16:13). This is true for Jesus Christ himself (Jn 12:49,50). Thus, all scripture came from God the Father via the Holy Spirit unto man.
The Old Covenant Has Ended
Until one accepts that the old covenant has ended, there is no way to convert them to Christianity. The Jews stumble at this biblical fact and so does every denomination in the world. This is why all denominations tithe, have instrumental music, and commit adultery with abandoment. The old testament foretold that it would end and a new covenant would be given. Jeremiah wrote, “Behold, the days are coming, says the Lord, when I will make a new covenant with the house of Israel and with the house of Judah — not according to the covenant that I made with their fathers in the day that I took them by the hand to lead them out of the land of Egypt, My covenant which they broke, though I was a husband to them, says the Lord” (Jer 31:31-32). The new testament is filled with infallible proofs that the old law, the law of Moses, the ten commandments, the law which God gave to Moses on Mount Sinai has ended.
Jesus has abolished the “law of ordinances” (Eph. 2:14-16). The law has “passed away” (2 Cor. 3:11). The law was “cast out” (Gal. 4:21-30). The law lasted “till the seed should come” (Gal. 3:19), which seed was Christ (Gal. 3:17). “You are not under the law” (Rom. 6:14). “You are dead to the law” (Rom. 7:1-7). The law was abolished. (Eph 2:15,16). Law was blotted out and nailed to the cross (Col 2:14) We are not justified by the law (Rom 3:19,20,28). We are not under the law (Rom 6:14,15). If righteous came by the law, Christ died in vain (Gal 2:21). The law was until John (Lk 16:16). The law was our schoolmaster to bring us to Christ (Gal 3:24,25). Christ is the end of the law (Rom 10:4). Christ redeemed us from the curse of the law ( Gal 3:10,13). Anyone justified from the law has fallen from grace (Gal 5:4). Thus, the old law has vanished away and the law of Christ governs a Christian’s life today (Heb 8:13).
We Are Forbidden to Add Or Subtract From The Word of God
Until one accepts that we are not allowed to alter God’s Word, our worship to God is in vain (Mt 15:7-9). It has been true since the dawn of time that man is not allowed to alter God’s Word whatsoever. Yet, despite this fact, most religions feel free to add to or take from God’s Word. This is why the Catholics and Mormons have their own bible and why protestant religions have their own manuals and man made doctrines.
God made it abundantly clear that he doesn’t allow anyone to change his Word. Moses commanded Israel, “You shall not add to the word which I command you, nor take from it, that you may keep the commandments of the Lord your God which I command you” (Deut 4:2) Also read: Deut 5:32 cf; 12:32; 28:14 Solomon wrote, “Do not add to His words, lest He rebuke you, and you be found a liar” ( Prov 30:6). The apostles had the same reverence to God’s Word in the new testament. They spoke only what they had seen and heard (Acts 4:19,20) .They taught only what the Holy Spirit revealed to them (1 Cor 2:13). They taught us not to go beyond that which was written (1 Cor 4:6). They commanded us to “Speak as the oracles (very words) of God” (1 Pet 4:11) They reminded us that the holy men of God spake as they were moved by the Holy Spirit (2 Pet 1:21). They gave us the consequences of changing God’s Word. “Though we, or an angel from heaven, preach any other gospel unto you than that which we have preached unto you, let him be accursed” (Gal 1:9) They warned us not to add to or take from God’s Word lest our name be removed from the Lamb’s book of life (Rev 22:18,19). Thus, it is conclusive that God strictly forbids anyone to change his Word!
Conclusion: Until the one you are teaching can accept these basic fundamentals of the scripture they cannot be saved; And if someone has been baptized into the churches of Christ and they reject either one of these basic principles they will not be accepted by God. However, once one has accepted these infallible proofs of the scripture, there is no way one cannot see and understand the gospel and doctrine of Christ and His apostles. “Then Jesus said to those Jews who believed Him, “If you abide in My word, you are My disciples (“Christians” Acts 11:26) indeed. And you shall know the truth (Jn 17:17), and the truth (Eph 1:13) shall make you free” (Jn 8:31-32). “Whatever you do in word or deed, do all in the name of the Lord Jesus, giving thanks to God the Father through Him” (Col 3:17).
