Salt and Seed: The CoVo Radical Middle

by Dave Miller

The co-vocational life is a calling to live as both salt and seed in the world, embodying the kingdom of God in the midst of the old creation and proclaiming the gospel with confidence, clarity, and consistency. 

Jesus said that His disciples are the salt of the earth (Matthew 5:13), meaning that our presence in the world is meant to preserve what is good, confront decay, and bring out the flavor of God’s design in a world spoiled by sin, death, and the curse. 

Salt does its work only when it is embedded into what is decaying. In the same way, co-vocational workers do not withdraw from the world, nor do they separate life into sacred and secular compartments. Instead, they enter the war zone of the old creation and live a kingdom reality in full view of those caught in decay. This is a life of intentional presence, demonstrating a better way, a kingdom way, in the everyday rhythms of work, leadership, community, and calling.

But Jesus also makes clear that we are more than preserving agents; we are sowers. In the parable of the four soils (Mark 4:1–20), Jesus describes the Word of God as seed that is scattered into the hearts of people. Some will reject it, some will receive it temporarily, some will be choked by the cares of the world, but some will bear fruit thirty, sixty, or a hundredfold.

This means that co-vocational life is not merely about living out the gospel as a quiet example. It is about proclamation, sowing the Word with intentionality, trusting that the seed has power and that God alone gives the growth (1 Corinthians 3:6). We do not control the soils, but we are responsible to sow. 

We refuse the lie that presence alone is enough, and we refuse the opposite lie that proclamation without presence is faithful. Salt without seed is stagnant. Seed without salt is shallow. But salt and seed together embody the fullness of the ambassador identity of the people of God.

The old creation is a battleground where sin still enslaves, where the flesh still deceives, and where the powers and principalities resist the advance of the kingdom (Ephesians 6:12). In this contested space, the co-vocational worker fights a different kind of battle. We do not wage war as the world does (2 Corinthians 10:3–4). 

We resist decay not with outrage, manipulation, or control but with holiness, integrity, kindness, courage, love, and truth as we walk in step with the Spirit (Galatians 5:16–25). We plant gospel seed through real conversations, intentional relationships, invitations to repentance and faith, and the bold declaration that Jesus is Lord (Romans 10:9–17). We endure as salt and we multiply the seed.

This vision protects us from the extremes that often cripple believers who live and work in the marketplace. Some bury their witness in silence, convincing themselves that gospel fruit will somehow emerge without gospel words. Others preach loudly but live in a way that contradicts the message, producing more confusion than clarity. Jesus gives no room for either. He sends His people into the world as visible, faithful presence and as vocal, faithful witnesses. Salt slows the rot; seed sparks the harvest. Salt fights back the effects of death; seed announces the arrival of life. Salt proves that another kingdom is possible; seed offers the only way into it.

When co-vocational disciples embrace this identity, everything changes. Work becomes worship (Colossians 3:23), calling becomes mission, relationships become entrustments, and the ordinary spaces of life become holy ground. 

We stop waiting for a platform and realize God has already given us one. 

We stop wishing for a different assignment and begin to steward the one we have. 

We stop seeing our job as a distraction from ministry and recognize it as the very field in which we have been sent to sow. 

The kingdom is at hand (Mark 1:15), and the King has placed His people in every sector of society so that the knowledge of the glory of the Lord might fill the earth as the waters cover the sea (Habakkuk 2:14).

Salt and seed is not a strategy. It is an identity grounded in the words of Jesus and empowered by the Spirit of God. Covocational workers carry the new creation into the old, confronting decay while announcing life, holding the line with faithfulness while advancing the mission with clarity. 

We embed. 

We proclaim. 

We endure. 

We multiply. 

This is the call. 

This is the work. 

This is the joy.
