How does Psalm 71:15 connect with the Great Commission in Matthew 28:19-20? Opening the Texts “My mouth will tell of Your righteousness, of Your salvation all day long, though I cannot know their full measure.” “Therefore go and make disciples of all nations, baptizing them in the Name of the Father and of the Son and of the Holy Spirit, 20 and teaching them to obey all that I have commanded you. And surely I am with you always, to the very end of the age.” Common Ground: Proclaiming God’s Saving Work • Psalm 71:15 pictures a believer who simply cannot keep silent about God’s righteousness and salvation. • The Great Commission calls every disciple to declare that same saving work—now revealed fully in Jesus—across the whole earth. • Both passages highlight word-centered witness: the psalmist’s “mouth” and Jesus’ “go…make disciples…teaching.” A Continual, Lifelong Calling • “All day long” (Psalm 71) stresses ongoing testimony, not a one-time event. • “Always…to the very end of the age” (Matthew 28) matches that sense of permanence; evangelism is the believer’s lifelong assignment. Content of the Message • Psalm 71 focuses on “Your righteousness” and “Your salvation.” • Matthew 28 unfolds that salvation in Trinitarian clarity—“the Father…Son…Holy Spirit”—and centers it on obedience to Christ’s commands. • Romans 1:16 reinforces the unified theme: “I am not ashamed of the gospel, because it is the power of God for salvation to everyone who believes.” Power Behind the Witness • The psalmist acknowledges he “cannot know” the full measure of God’s works—yet he trusts God to use his limited words. • Jesus answers that limitation by promising His abiding presence: “I am with you always.” • Acts 1:8 echoes the supply of divine power: “You will receive power when the Holy Spirit has come upon you, and you will be My witnesses.” Old Testament Anticipation, New Testament Commission • Psalm 71 anticipates a people eager to announce Yahweh’s deliverance. • Matthew 28 shows the fulfillment—Christ’s finished work and the Spirit’s empowerment turn that anticipation into a global mandate. • Psalm 96:2-3 carries the same trajectory: “Proclaim His salvation day after day…declare His glory among the nations.” Practical Takeaways • Keep the gospel on your lips daily—family, workplace, community. • Root your testimony in God’s righteousness, not personal anecdotes alone. • Expect Christ’s presence; evangelism is never a solo effort. • Move from private praise (Psalm 71) to public disciple-making (Matthew 28); both belong together. • Let the immeasurable scope of God’s salvation fuel humility and urgency. In Short Psalm 71:15 supplies the heart; Matthew 28:19-20 provides the marching orders. One text captures the overflow of gratitude, the other channels it into worldwide disciple-making—both celebrating and spreading the same unchanging salvation. |
