Yes, there are times when we feel as if we are being swallowed up by our troubles. Yes, there are times when we want to choke the living daylights out of those troublemakers. Yes, those anxious moments make us sweat and question 'is it worth it?'
Kick that doubt out the door and never give up. If you still have breath, then use the fight still left in you. 'Greater is He that is in you, than in the world.' God gives us trials to make us stronger in Him. 'Out of my distress, I called upon the Lord; He answered me and set me free.' Psalm 118;5 Abraham responded to his doubt and fear with faith, unquestioning action, and prayer. How do you respond?
Trials are not a coincidence, they have purpose. 'God leads us to troubled waters, not to drown us but to cleanse us.' Let Him finish the work He started in you and don't give up on Him or yourself.
