All genuine Christians have believed on Christ because they realized He was the holy Lamb who was the sacrifice for them as born sinners and the sins they commit. However, they also must continue their Christian walk according to that knowledge of His holiness. As they have received Christ Jesus the Lord, they do walk in Him.
8 A highway will be there, a roadway,
And it will be called the Highway of Holiness.
The unclean will not travel on it,
But it will be for him who walks that way,
And fools will not wander on it.
9 No lion will be there,
Nor will any vicious beast go up on it;
These will not be found there.
But the redeemed will walk there,
10 And the ransomed of the Lord will return
And come with joyful shouting to Zion,
With everlasting joy upon their heads.
They will find gladness and joy,
And sorrow and sighing will flee away. Isaiah 35:8-10 (NASB)
5 This is the message we have heard from Him and announce to you, that God is Light, and in Him there is no darkness at all. 1 John 1:5 (NASB)
God is holy and immutable. There is not now nor has there ever been nor will there ever be any darkness in Him. He is eternally holy. In James 1:17 we read that with God, there is no variation or shadow due to change. The Puritans referred to God as the “Thrice Holy God!” Peter tells us in 1 Peter 1:14-19 that the redeemed of the Lord are commanded to be holy as He is holy then he tells us why and how we are to do so.
14 As obedient children, do not be conformed to the former lusts which were yours in your ignorance, 15 but like the Holy One who called you, be holy yourselves also in all your behavior; 16 because it is written, “You shall be holy, for I am holy.”
17 If you address as Father the One who impartially judges according to each one’s work, conduct yourselves in fear during the time of your stay on earth; 18 knowing that you were not redeemed with perishable things like silver or gold from your futile way of life inherited from your forefathers, 19 but with precious blood, as of a lamb unblemished and spotless, the blood of Christ. 1 Peter 1:14-19 (NASB)
Christians who are walking according to the flesh, which is being conformed to their former ignorance, are not walking according to the spirit. What is not of faith is sin. (Romans 14:23) When believers walk according to the flesh they are seeking fulfillment from the world. This is sin. Therefore, to be holy is to walk in accordance to our sanctification. Sanctification is the act of God removing His flock from sin. God is intimately involved in our sanctification, but our role in it is not passive.
18 In the exercise of His will He brought us forth by the word of truth, so that we would be a kind of first fruits among His creatures. James 1:18 (NASB)
All in Christ are begotten of God. This is speaking in part of our regeneration where the word of truth is written on our hearts as His grace, in accordance with our faith, quickened us from spiritual death unto eternal life. Therefore, we are to “lay aside every weight and sin as we run the race God has set before us.” (Hebrews 12:1-2) We are commanded to cleanse out the old leaven from our hearts. Why? For Christ our Lord, our Passover Lamb, has been sacrificed.
7 Clean out the old leaven so that you may be a new lump, just as you are in fact unleavened. For Christ our Passover also has been sacrificed. 1 Corinthians 5:7 (NASB)
1 Therefore, having these promises, beloved, let us cleanse ourselves from all defilement of flesh and spirit, perfecting holiness in the fear of God. 2 Corinthians 7:1 (NASB)
Much of the teaching in “churches” these days never speak of these things. The emphasis is on the “Social Gospel” or the “Feel Good and Be Positive Gospel” or the “Be Healthy and Wealthy and Prosperous Gospel.” I believe that God is drawing His sheep into the light in these last days because time is short. The end of this age is swiftly approaching. We are being prepared. We must understand what it means that Christ is our Passover sacrifice. Because we believe on Jesus Christ, His righteousness has been imputed to us and we also received justification. God the Father has declared us righteous; therefore, we have entered a relationship with Him as though we have never sinned.
