“Whether Christ acknowledges a person to be His or not and confesses Him before His Father, who is in heaven, determines everyone’s lot (Matt. 10:32-33). Our acquittal and salvation depend upon His public confession.
Christ was not ashamed of us at His incarnation. To be sure, He had many reasons to be. He Himself was the firstborn of the Father, the radiance of the Father’s glory and the exact image of His being– who thought it not robbery to be equal with God (John 3:16; 10:30; 17:5; Heb. 1:3; Col. 1:15; Phil. 2:6).
We were laden with guilt, unclean from head to toe, and subject to decay (Ps. 38:4; Rom. 8:20-21), yet He was not ashamed to call us His brothers (Heb. 2:11). He was not ashamed of us before God or before the holy angels (Mark 8:38).
He took on our flesh and blood, assumed our nature, and became like us in everything apart from sin. In Christ, even God was not ashamed to be called our God (Heb. 11:16).
Therefore, He will likewise not be ashamed of us in the day of His future. To be sure, at that time He will come again not as a servant but as Lord, not to suffer but to be glorified, not to a cross but with a crown (Rev. 6:2; 19:16).
Nevertheless, He will not be ashamed of us, for the One who ascended far above the heavens is the same One who descended to the lowest parts of the earth. The One who judges is the Son of Man who once came to seek and to save the lost (Luke 19:10).
Our Judge is our Savior; He never forgets nor forsakes His people (Deut. 31:6; Isa. 33:22). ‘So everyone who acknowledges Me before men, I also will acknowledge before My Father who is in heaven’ (Matt. 10:32).
In full view of the whole world so that all of creation may hear it, He will publicly stand up for His faithful confessors. However despised they may have been in this world, Christ will take their name upon His lips and proclaim it to every ear that they are His– the ones whom He has bought with His own blood and of whom no power in the world or in Hell will be able to rob Him (Rom. 8:38-39).
As Christ says, so it will be. His judgment will apply to the whole of creation. His confession will concern all creation. No one will be able to criticize it. No one will dare to oppose it. His judgment will be exalted above all criticism and will stand high above the judgment of all men and devils. The heavens and the earth and Hell and all creation will eternally submit to it.
Of greater importance than all of this is that the Father will rest in this work of His Son (Heb. 4:9-10). Just as after creation God saw all that He had made and, behold, it was very good, in that way at the end of days He will look down with divine pleasure upon the great work of redemption that Christ accomplished (Gen. 1:31).
When the church without spot or wrinkle is set before Him, and the perfected kingdom has been given to Him, then the Father will adopt all of the redeemed of the Son as His children, inviting them to participate in His communion and enjoy His presence (Eph. 5:25-27; Rev. 21:2, 7).
The public confession on behalf of believers by Christ before His Father, who is in heaven, will be the guarantee of their eternal salvation and glory (Matt. 10:32).”
