Those are worldly plans, and they do not figure into God's plan and priorities. We must make His will paramount. His ways are not our ways. When we attempt to subjugate our will towards His, we are in conflict with Him.
Don't get me wrong: planning on playing with your grandchildren is a good thing. And God will give us the fullness of our lives in the time we have, but we must never ask that He delay His plan for ours.
I remember hearing a sermon about a pastor talking to some women, telling them that Jesus could return at anytime. Some of them said they looked forward to His return, but "not before I travel, and other things I want to do."
I have a few things that need doing here before I leave.
“Those are worldly plans,”
That’s not necessarily the case. There is perhaps work we would like to do in service to the Lord, before departing.
