You probably have Matthew 28:18 – 20 memorized. You know that the promise that accompanies that command is the Lord will be with as we obey to the end of the age. I my reading in the past month I have seen that theme thread through the Bible.
Exodus 3:11 – 12
John 16:7 – 15
The implications seem to be that when He calls us or assigns us a task, ministry, etc. He is there with us throughout.
Some of the tasks are difficult. I am pretty sure that without His presence, I would fail.
