1. Walk in holiness and uprightness. When God renewed His covenant with Abraham, He makes this the preamble of it, "I am the Almighty God, walk before Me, and be thou perfect, and I will make My covenant between Me and thee." As this must be a covenant of salt, in regard of faithfulness; so there must be salt in this covenant, even the salt of holiness and uprightness. The Jews were commanded in all their offerings to use salt; and that is called the salt of the covenant, "Every oblation of thy meat-offering shalt thou season with salt, neither shalt thou suffer the salt of the covenant of thy God to be lacking." What is meant by salt on our parts, is taught us by Christ Himself, "Have salt in yourselves, and have peace one with another." Which I take to be parallel in sense with that of the apostle, "Follow peace with all men and holiness." As salt, the shadow of holiness, was called for, in all those Jewish services; so holiness, the true substantial salt, is called for in all ours. As then it was charged, "Let not the salt of the covenant of thy God be lacking:" so now it is charged, "Suffer not the salt of thy covenant with God and His people to be lacking." Seeing we have made a covenant of salt, that is, a sure covenant, let us remember to keep salt in our covenant. Let us add salt to salt, our salt to the Lord's salt, our salt of holiness to His salt of faithfulness, and we shall not miscarry. 2. Walk steadily or stedfastly in this covenant. Where the heart is upright and holy, the feet will be steady. Unstedfastness is a sure argument of unsoundness, as well as a fruit of it. "Their heart was not right with Him; neither were they stedfast in His covenant." As if He had said, would you know the reason why this people were so unstedfast? It was, because they were so unsound. "Their heart was not right with Him." We often see the diseases of men's hearts breaking forth at their lips, and at their finger ends, in all they say or do.
