Very understandable feelings.
Increasingly . . . ONLY WHAT’S DONE FOR CHRIST will last.
It’s always been true. Never truER than now.
Yet, throwing in the towel is not the Godly thing to do, either.
One just has to follow Holy Spirit’s wisdom day by day, moment by moment, context by context, imho.
The Lord says to occupy until I come, not toss the towel in the ring and quit.
