The Blood of Jesus has laid the path for holiness

For example, when the Christians in Corinth were struggling to understand the difference Christ had made in them, the apostle Paul gave a laundry list of sinful behaviors and reminded the Corinthians that the unregenerate, the unchanged and those unmoved by the gospel would not inherent the kingdom of God (1 Cor. 6:9-10). But then he says, "And such were some of you. But you were washed, you were sanctified, you were justified in the name of the Lord Jesus Christ and by the Spirit of our God" (1 Cor. 6:11, emphasis added).
The Blood of Christ has secured our holiness in the sight of God. Because the blood of Christ has been shed for us, our position in the eyes of God is secure. We are in Christ, and we are holy as He is holy (1 Cor 1:30).
Nevertheless, there is the ongoing work of Christ in making us practically, namely, holy. In other words, there will be times in our lives when we do not feel the ongoing, progressive nature of our sanctification. We may even get the sense that rather than progressing, we are regressing due to our perpetual struggle with indwelling sin. It is during such times that the gospel reminds us that our sanctification is not because we are willing to shed Christ's blood but because Christ was willing to shed His. It is not our blood and sacrifice that has pleased the Father; it is the blood of His beloved Son. Thus, when the battle for daily holiness appears lost, encourage yourself with the words for the old saints: "I ain't what I wanna be; I ain't what I'm gonna be; but through the blood of Christ, I ain't what I once was."
Satan knows our weaknesses, and he often sees when we fail. He is quick to remind us of our lack of progress in the Gospel and how often we appear halted in our conformity to Christ. When this is the case, consider the words of Augustus Toplady: "When Satan tempts me to despair and tells me of the guilt within; upward I look and see Him there, who made an end to all my sin."
He made an end to all our sin by suffering as our sin offering outside the gate (Lev 4:21).
So, keep moving Christian. The Bible remind us that "what we will be has not yet appeared; but we know that when he appears we shall be like him, because we shall see him as he is" (1 John 3:2). In other words, God is not through with us yet.
