“Hear my prayer, O Lord, give ear to my supplications: in thy faithfulness answer me, and in thy righteousness. And enter not into judgment with thy servant: for in thy sight shall no man living be justified” (Psalm 143:1-2 KJV).
David asked God to hear his prayers, knowing that he, like all men, was worthy of death. You see, all of us fall short of the glory of God (Romans 3:23), and are incapable of standing in the presence of a Holy God – on our own merit. We have all been judged guilty for our sin and are deserving of punishment – which is death.
“For the wages of sin is death; but the gift of God is eternal life through Jesus Christ our Lord” (Romans 6:23).
But when we put on the righteousness of His Son Jesus Christ, His righteousness is what God sees when He looks at us.
"And do this knowing the time, that now is the hour to awake out of sleep, for now is our salvation nearer than when we believed. The night is far spent. The day is at hand. Let us therefore cast off the works of darkness and let us put on the armor of light. Let us walk honestly as in the day, not in carousing and drunkenness, not in immorality and shamelessness, not in strife and envyings, but put ye on the Lord Jesus Christ and make no provision for the flesh to fulfill its lusts" (Romans 13:11-14).
That is really what a Christian is to be, one who is cloaked, who is clothed, who is garmented with the character, the disposition, the attitude, the habits and the virtues of Jesus Christ. We are clothed in the righteousness of Christ when we surrender our will to that of the Father, and allow the Holy Spirit to transform us into the image of His Son Jesus Christ.
Blessings to you all!
