Mark 16:20 Meaning: When the Lord Works with Us

Two Greek verbs carry the weight of this verse. The first is sunergeō, translated “working with them.” It means to put forth power together with someone, to be a partner in the work. This word appears only here in the Gospels, but Paul uses it often, he speaks of God working all things together for good, and of believers as workers together with God. The apostles were not alone. The Lord was right there beside them, lending his own strength to every word they spoke.

The second verb is bebaioō, “confirming.” It means to make firm, to establish something so it cannot be shaken. The message they preached did not rest on their eloquence or arguments. God himself set it in place, making it trustworthy.

And he did so through sēmeia, signs. A sign is not magic; it is something that points beyond itself. The healings, the changed lives, the courage in the face of suffering, all of these were visible markers that said: this message is from God.

Christians have read this verse in different ways. Some see the signs as miraculous confirmations unique to the apostolic age, raising the dead, healing the sick, speaking in tongues, which verified the gospel before the New Testament was complete. Others believe the Holy Spirit continues to give such gifts today, as the Lord still works through his church.

A number of commentators, like Adam Clarke, point out that while miraculous signs may no longer be required, the deeper co-operation of God remains essential. Without his work in the heart, no preaching saves a soul. Across traditions, Christians agree on the main point: the Lord himself is the one who makes the message stick.

Some read “signs following” and think every Christian must experience dramatic miracles for their faith to be real. But the Greek word for “following” (epakoloutheō) simply means accompanying, the signs came alongside the preaching, not as a requirement for every believer. In fact, the Lord confirmed the word with signs, not the believer’s worthiness. The focus is on God’s action, not our experience.

You might not stand before a crowd this week. But you will have moments to speak about what Jesus means to you, with a friend, a family member, a coworker. In those moments, the Lord is working with you. You do not have to produce results. Your job is to speak. His job is to confirm. The confirmation may not be a visible miracle. It could be the quiet conviction in someone’s heart, a question they ask weeks later, or the way your words linger in their mind. Trust him to do what only he can do.
