I’m on my way. This is what we hear often from those who are expected to be somewhere but are not there yet. They are certainly coming and are on their way. They may have already left and might actually be on the road very close. Or, they might still be at their previous location, thinking about heading out soon, but not really planning to arrive for a while. Either way, they are coming and will make it to the destination eventually. There is no need to worry, but just to be ready and be patient.
I was recently reminded that I could see the return of Jesus with this same mentality. Jesus is certainly coming and will eventually arrive, but only God knows when. We should be ready for His arrival at any time, but not be too put off it if is taking longer than we expect.
