I was taking a deep reflection on my little bed and a portion from the book of Isaiah chapter 40 and verse 29 in particular the contemporary English version quotes the passage thus
"giving power to the tired and reviving the exhausted "
I draw from this text that getting tired is not a sign of weakness and getting exhausted is not a crime or weak faith. In fact, it is those who are tired and exhausted that God will give strength to.
Are you weak tired and exhausted, it is you yes you in particular God wants to give strength to.
Be encouraged, strength is awaiting you from the Lord.
