“Older saints, please press on. You have walked the path of faith longer than us newbies, and although sin still sways your ways and thoughts, your many small victories of faith can greatly encourage us young wanderers. There is nothing wrong with being young (1 Timothy 4:12), but there is nothing wrong with being old, either. God isn’t alarmed by your aches and pains or lack of energy. Plus, we younger Christians need you more than we let on.
Don’t give up. There is no age limit for kingdom work.”
