3 And behold, Moses and Elijah appeared to them, talking with Him. 4 Then Peter answered and said to Jesus, “Lord, it is good for us to be here; if You wish, let us make here three tabernacles: one for You, one for Moses, and one for Elijah.” 5 While he was still speaking, behold, a bright cloud overshadowed them; and suddenly a voice came out of the cloud, saying, “This is My beloved Son, in whom I am well pleased. Hear Him!” (Matthew 17:3–5, NKJV)
The Word (Christ) did not cling to the “form of God” when He became flesh (Phil. 2:5-7). That is, He emptied Himself of the glorious appearance of deity He shared with the Father “before the world was” (Jno. 17:5; Jno. 1:1, 14). Without divesting Himself of His Godhood, He took the “form of a bondservant” and became human (Phil. 2:7). His humility reached its zenith when He obediently died on the cross (Phil. 2:8). On the mountain, when Jesus was transfigured, Peter, James, and John saw a glimpse of His glory and heard the Father’s confirmation of His Sonship (Matt. 17:1-2; Lk. 9:32; 2 Pet. 1:16-17). Jesus is superior to the Law (Moses) and the prophets (Elijah). Therefore, we must hear the Son in everything He teaches (Acts 3:22-23). That means we go to His New Testament to inform and activate our faith, not to the Old Testament law and prophets (Heb. 1:1-2). We listen to the Son by hearing and accepting His apostles’ teachings (Jno. 13:20; Matt. 28:19-20). Are you listening to the Son of God?
7 For if that first covenant had been faultless, then no place would have been sought for a second. 8 Because finding fault with them, He says: “Behold, the days are coming, says the Lord, when I will make a new covenant with the house of Israel and with the house of Judah—” (Hebrews 8:7–8, NKJV)
We are not under the Old Testament law today. The first covenant (the Sinai covenant God commanded Israel) “made nothing perfect” (Heb. 7:19). That is, the law given through Moses, with all its animal sacrifices and offerings, could not “take away sins” (Heb. 10:1-4). In this sense, it was weak and unprofitable (Heb. 7:18). This was not the law’s fault, for it was not designed to be the sinner’s mean of justification and redemption. If it were, then Jesus died in vain (Gal. 2:21). The law (first covenant) was a “tutor” to bring sinners to Christ, to be “justified by faith” (Gal. 3:24). It was added to the Abrahamic promise “because of transgressions” (Gal. 3:17-19). The first covenant exposed the sinfulness of sin, and by doing so, turned men to God for divine mercy (Rom. 3:20; 7:13; 11:30-31). Now, Christ has mediated a “better covenant,” established on “better promises” (Heb. 8:6). The new covenant (the New Testament) dispenses merciful forgiveness and an eternal inheritance (Heb. 8:12). Here is a fundamental reason why we are not under the Old Testament law. It was a shadow of what has now been accomplished in Jesus Christ. It has passed away (Heb. 10:1; 8:13).
