“And they shall teach no more every man his neighbor, and every man his brother, saying, Know the Lord: for they shall all know Me, from the least of them unto the greatest of them, saith the Lord.” -Jeremiah 31:34
Truly, whatever else we do not know, we know the Lord. This day is this promise true in our experience, and it is not a little one. The least believer among us knows God in Christ Jesus. Not as fully as we desire; but yet truly and really we know the Lord. We not only know doctrines about Him, but we know Him. He is our Father and our Friend. We are acquainted with Him personally. We can say, “My Lord, and my God.” We are on terms of close fellowship with God, and many a happy season do we spend in His holy company. We are no more strangers to our God, but the secret of the Lord is with us.
This is more than nature could have taught us. Flesh and blood has not revealed God to us. Christ Jesus had made known the Father to our hearts. If, then, the Lord has made us know Himself, is not this the fountain of all saving knowledge? To know God is eternal life. So soon as we come to acquaintance with God we have the evidence of being quickened into newness of life. O my soul, rejoice in this knowledge, and bless thy God all this day!
