Maybe not, but if (through our own fault) we find we can't keep Jesus' commandments, we might still find we can keep returning to them.
That's not our end goal, of course. But it might be the means to the goal. After all, "If we acknowledge our sins, he is faithful and just and will forgive our sins and cleanse us from every wrongdoing."
"You are witnesses of these things."
The disciples had been with Jesus and seen His works, His death, and now even His resurrected body.
But they are not merely observers. They are witnesses. A witness sees, and then reports.
I wonder if the disciples realized, as they followed Jesus in the heady days in Galilee, that they were in training for their new vocation as witnesses to all the nations.
And of course, we all know that "witness" is just the English word for the Greek "martyr."
We who have seen don't have a choice. We must also report; we must be witnesses. IF we are not witnesses to the nations, then our very silence will one day be witness against us.
