In his farewell address to the nation Israel, Moses said:
βAsk now of the days that are pastβ¦ since the day that God created man upon the earth, and ask from the one side of heaven unto the other, whether there hath been any such thing as this great thing is, or hath been heard like it? Did ever people hear the voice of God speaking out of the midst of the fire, as thou hast heard, and live?β (Deut.Β 4:32,33).
Moses referred, of course, to the giving of the Law, when God spoke to Israel by word of mouth amid the lightnings and thunders of Sinai. In Israelβs case alone βGod spake all these wordsβ audibly. Never before had He undertaken to address a nation personally.
This was indeed a great honor for Israel, but God has since spoken to all mankind in an even more striking manner, for in Heb. 1:1,2 we read:
βGodβ¦ hath in these last days spoken unto us by [in] His Sonβ¦ whoβ¦ when He had by Himself purged our sins, sat down at the right hand of the Majesty on high.β
At Sinai God spoke the words of the Law, but now, in Christ, He speaks of mercy and grace. There He spoke of the righteousness which He demands, but here He tells of the righteousness which He provides in Christ.
Some suppose that the absence of miraculous demonstrations, the want of divine intervention in the affairs of men, etc., indicate indifference on Godβs part, but actually this apparent indifference speaks to us of His love and grace.
Remember, the Psalms and all prophecy had predicted Godβs judgment upon men for their rejection of Christ, yet today the Son still remains a voluntary Exile from His own world, while neither He nor the Father do anything to avenge His cruel crucifixion. Meanwhile, still lingering in mercy, He sends His ambassadors to offer reconciliation to His enemies by grace through faith. Thus His silence actually cries: The door of grace is still open. Be reconciled while you may. βBelieve on the Lord Jesus Christ and thou shalt be savedβ (Acts 16:31). source
