We now come to what is often called “the sermon on the mount.” The Lord Jesus tells His people the principles (rules) of the kingdom that He had come to set up. But He, the King was rejected and crucified. The kingdom has been postponed, so that although we read these beautiful verses, we know that they have not yet been fulfilled.
V.5 Are the meek inheriting the earth today? No, but the wicked and ungodly are. Remember that after the believers are taken to glory (maybe today), the Lord shall return to set up this kingdom.
V.11-12 If we wish to be faithful to the rejected One, we also may find ourselves persecuted and falsely accused for the Lord’s sake. We can rejoice and be exceeding glad. Although these instructions were so sweet and perfect, yet it is Himself, blessed Lord Jesus, that has the power of attraction for us. If you have the time, read Deuteronomy 14 for the connection of Israel with the Old Testament and see how our chapter was spoken to this same nation. Then read Galatians 3:12-1312And the law is not of faith: but, The man that doeth them shall live in them. 13Christ hath redeemed us from the curse of the law, being made a curse for us: for it is written, Cursed is every one that hangeth on a tree: (Galatians 3:12‑13) to understand what grace has done for us.
V.17-48 The Lord Jesus speaks of the law of Moses. He not only confirms the authority of these laws, but He speaks of the heart of man. The law of Moses only took notice of actions, but God looks at the heart. Man is more responsible today than he was while under the law of Moses.
V.22 It was very wrong to be angry with one’s brother.
V.27-28 That which is hidden in the heart of people is known to God.
V.33-37 It is very common today for people to swear in order to make their statements more sure. Such language is not at all pleasing to Him.
V.38-48 This is what the Lord delights to see in those who wish to please Him. This was the way in which He Himself acted when He was here. There is no one who loved His enemies like the Lord Jesus.
