22 But prove yourselves doers of the word, and not merely hearers who delude themselves. 23 For if anyone is a hearer of the word and not a doer, he is like a man who looks at his natural face in a mirror; 24 for once he has looked at himself and gone away, he has immediately forgotten what kind of person he was. James 1:22–24, NASB
How important is obeying the words of Christ? This is, of course, the essence of Lordship. Jesus Christ is Lord. That is not just a title nor is it something we say to revere him. No, He is Lord over all. He is one in essence with God the Father and God the Holy Spirit in the Hypostatic Union of the Holy Trinity. God is Sovereign and because of his role in the Hypostatic Union, his submission in humbling himself to become a man, the Messiah, his obedience to the Father’s will in all of this as well as keeping the Law perfectly, he also, at the perfect time ordained by the Father, laid down his life as the propititiation for those he came to save.
