Rom7:7, Gen3:4, 2Cor3:6, Gal3:29, Ex32:28, Acts2:41.
The law was given to reveal how feeble we are after man got exposed to the knowledge of good and evil. Man became a dead person because there was no way he could fullfil the requirements of the law by himself to be right with God.
That's why on mount Sinai we realized that 3000 people perished after the law was given. But on Mount Zion, at the given of the spirit which is the grace of God, 3000 souls got saved. This points to the truth that grace will always give life but the letter kills.
Brethren, Where do you stand? Mount Zion or Mount Sinai? Remember if you're Abraham seed then you're Christ's, and for that reason you stand on Mount Zion, where the grace of God flows profusely to give us eternal life. Shalom.
