When God chose his people to be with them he needed to teach them out of all the lesson, three umbrella type lessons. Lessons that would be embedded into their conscience and passed down from generation to generations, were the ones God was going to teach them. And, when the people were in bondage for 400 years he sent Moses to begin those lessons. One of the lessons God taught his people was that he is who he says he is, and when the people asked Moses who had sent him he told them “I am That I Am” sent me (Ex3:14). The authenticity of God is important for the believer to have embedded in order for him to persevere in God’s kingdom. And, this lesson was learned as the people witnessed the 10 plagues and the crossing of the red sea. They learnt this lesson by watching what God was doing. The second lesson God taught his people was that he does what he says he is going to do (Num23:19). Each plague God told Moses that he was going to bring he brought it, and the people were a witness to this.
13 For if the blood of bulls and of goats, and the ashes of an heifer sprinkling the unclean, sanctifieth to the purifying of the flesh: 14 How much more shall the blood of Christ, who through the eternal Spirit offered himself without spot to God, purge your conscience from dead works to serve the living God?
The third lesson that people of God were taught is that he does not like sin, but that there is forgiveness in him when we fail (ps130:4). Through the sprinkling of blood from a calf or lamb in the holy of holy place in the tabernacle on the book and on the people, their flesh were cleansed and forgiven for whatever they had done that year. This was done once a year every year by the high priest, and eventually became engraved into the people’s conscience. The old testament was a mirror or shadow of what to come (He8:5). Once Christ presented his own blood for our sins; it was a once and for all deal, our conscience were made free from the past. But, what is the conscience? It is that part of the human psyche that elicits either a positive or negative feeling based on our works and on our morals. Now there are many things that come into our minds and are probably embedded unto our conscience; lessons, ideas or works that affect it negatively are considered dead works, things that are done without faith that are considered dead works (Ja 2:20). Paul tells us that it is essential that we have a renewing of our mind (Ro12:2) in order for us to know the will of God. He associates our conscience with the inner man that needs to be renewed daily (2Cor4:16). Paul states that if any man is in Christ he is a new creation and the old things have become new (2Cor5:17).
And God said unto Moses, I Am That I Am: and he said, Thus shalt thou say unto the children of Israel, I Am hath sent me unto you.
They serve a copy and shadow of what is in heaven. This is why Moses was warned when he was about to build the tabernacle, “See to it that you make everything according to the pattern shown you on the mountain.”
20 But wilt thou know, O vain man, that faith without works is dead?
And be not conformed to this world: but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect, will of God.
2 Corinthians 4:16
For which cause we faint not; but though our outward man perish, yet the inward man is renewed day by day.
