The law, the tablets of the Testimony, were given to Moses up on Mt. Sinai as He communed with the Lord. It was an etched stone Testimony of God's terms of relationship with His people. As Moses returned to camp, he found the people had corrupted themselves with idol worship. (Exodus 32.) The people had broken their relationship with the Lord. The tablets were smashed, the idols were destroyed, and the Lord declined to walk with His people anymore lest they should be destroyed by His presence! This is what the law says.... "You sin, you die, period!"
The people mourned and repented of their sins. (Exodus 33) Moses interceded on their behalf. (Moses is a picture, a type, of Christ.
New tablets were issued. (Exodus 34.) The covenant relationship was restored. This time the people got a glimpse of God's true nature. The new set of the tablets of the Testimony were given as a result of God's mercy, grace, and forgiveness! Moses' face glowed with the glory, mercy, and grace of God after he came down the mountain with the second set of tablets. The people were afraid to come near him. Then Moses put a veil on his face.
The veil covers God's true nature and makes it impossible to have a relationship with Him. Christ removed the veil when He died on the cross. Matthew 27:50 Jesus, when he had cried again with a loud voice, yielded up the ghost. 51 And, behold, the veil of the temple was rent in twain from the top to the bottom; and the earth did quake, and the rocks rent; 52 And the graves were opened; and many bodies of the saints which slept arose,
The only way to experience a true relationship with God is to remove the veil. This is done by repenting and trusting in the One that He sent, Jesus Christ. Jesus will remove the veil and you will experience a new and wonderful relationship with the creator of the universe. You will come to know His mercy, His grace, His love, His care, His peace, His guiding hand.
