People are born alienated from God and are His enemies until they are reconciled to Him through the blood of Christ (Rom. 5:1; 2 Cor. 5:18). No mere man could accomplish this peace; only the fully human and fully divine God-man could bring all things together through Himself.

Paul here again addresses renewal in Colossians 1:21 in the context of reconciliation and transformation through Christ.

Here's the verse for context:

"And you, who once were alienated and hostile in mind, doing evil deeds,"

In the broader passage (Colossians 1:21-22), Paul continues:

"he has now reconciled in his body of flesh by his death, in order to present you holy and blameless and above reproach before him."

Renewal is found in this passage through several key concepts:

1. Alienation and Hostility: Paul acknowledges that believers were once alienated from God and hostile in their minds, engaged in evil deeds. This highlights the need for renewal and transformation.
2. Reconciliation through Christ: Paul emphasizes that through Christ's death and resurrection, believers are reconciled to God. This reconciliation is the foundation of renewal, as it restores the broken relationship between humanity and God.
3. Holiness and Blamelessness: The goal of this reconciliation is to present believers as holy, blameless, and above reproach before God. Renewal involves a transformation of character, moving from a state of sinfulness to one of righteousness and purity.
4. Ongoing Process: The renewal described here is an ongoing process that begins with reconciliation and continues as believers grow in their faith and live according to God's will.

By embracing the reconciliation and transformation offered through Christ, believers experience renewal that leads to a restored relationship with God and a life characterized by holiness and righteousness.

Stay strong and be blessed.
