Passage
teaching them to observe all things whatsoever I have enjoined you. And behold, *I* am with you all the days, until the completion of the age.
teaching them to observe all things whatsoever I have enjoined you. And behold, *I* am with you all the days, until the completion of the age.
Matthew 28:18 And Jesus coming up spoke to them, saying, All power has been given me in heaven and upon earth.
Matthew 28:19 Go [therefore] and make disciples of all the nations, baptising them to the name of the Father, and of the Son, and of the Holy Spirit;
Matthew 28:20 teaching them to observe all things whatsoever I have enjoined you. And behold, *I* am with you all the days, until the completion of the age.
The verse centers on "all things", "teaching", "observe", "whatsoever", "enjoined", "behold", "days", and "until". It is saying that the verse draws attention to "all things" and "teaching", so its meaning should be read from those terms before moving to application.
The prior verse says "Go therefore and make disciples of all...", giving immediate footing for "all things" and "teaching". In Matthew context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "all things" and "teaching" with trust shaped by these words, not by a vague optimism outside the passage.
