Home > Jesus is God in Mark's Gospel
While the earlier chapters focus on Jesus’ earthly ministry, this verse reveals His ontological equality with the Father and cosmic reign.
Mark 16:20: "And they went out and preached everywhere, while the Lord worked with them and confirmed the message by accompanying signs." (v. 20)
This can be cross referenced with Matthew 28:18–20; Luke 24:50–53; Acts 1:1–11 and Hebrews 2:3–4.
"And they went out and preached everywhere, while the Lord worked with them..."
Throughout the Gospel of Mark, the title "Lord" (Kyrios) has been building in intensity. In the Septuagint (the Greek Old Testament), Kyrios is the standard substitute for the Tetragrammaton (YHWH).
By the end of the Gospel, "the Lord" is no longer just a respectful address for a teacher; it is the absolute title for the One who has triumphed over death and resumed His heavenly throne. The "Lord" who worked with them is the same "Lord" David addressed in Psalm 110 (Mark 12:36). Sitting at the "Right Hand" (Psalm 110:1) means sharing the singular identity, throne, and glory of YHWH. If Jesus is not YHWH, then assigning Him this level of authority is baseline Jewish blasphemy.
"...and preached everywhere, while the Lord worked with them..."
The verse states the disciples went "everywhere," yet the Lord was with all of them simultaneously. This is a clear claim of Omnipresence which is an incommunicable attribute of God (an attribute that belongs only to the divine essence and cannot be given to a creature).
A human teacher, even a resurrected one, is bound by space and time. However, Jesus is depicted as being present with every disciple in every location at once. This fulfills the promise in Matthew 28:20 ("I am with you always") and demonstrates that Jesus possesses the unique attribute of God to be everywhere present and every where active.
"...the Lord worked with them..."
The Greek verb synergeō indicates a "working together." In biblical theology, the primary "Worker" in the spread of truth is God Himself.
Jesus is not a passive figure waiting in heaven; He is the active Agent behind the mission. He is the one who opens hearts, provides the words, and directs the path. This "synergy" places Jesus in the role of the Divine King who directs His kingdom from the throne of Power.
By making Jesus the active force working with them, Mark places Jesus directly into the Old Testament role of God Most High.
"...and confirmed the message by accompanying signs.
In the Old Testament, signs and wonders are the "credentials" of God. God used signs to confirm the commission of Moses and the prophets.
Here, it is Jesus who provides the signs to confirm the word about Himself. He is both the subject of the message and the source of the miraculous power that validates it. If Jesus were merely a man, He could not "confirm" anything from the grave or from heaven; only God can manipulate the physical laws of creation to provide "accompanying signs.
Jesus acts with intrinsic authority: He confirms His own word with His own power. He is both the subject of the message and the source of the miracle, a dynamic that is impossible for a mere creature.
Mark 16:20 serves as the final rebuttal to "Low Christology." It presents a Jesus who is not only alive but is reigning and active.
The transition from the "suffering servant" of the earlier chapters to the "working Lord" of the finale shows that the mission of the Church is not the memory of a dead man, but the ongoing work of the Incarnate God, not the sentimental memory of a dead martyr.
