There is ALWAYS hope. Always! God never gives up on us.
What had Sampson done?
At the moment he lost his strength, he'd allowed another person to annoy him so much he shared his heart with her, secrets he shouldn't have shared. It cost him his ministry, his strength, his influence, his job (as spiritual judge leader).
Besides that he'd been using prostitutes, doing a lot of things that are definitely not good choices.
People would have given up on him.
God didn't. As the verse above says, "However, the hair of his head began to grow again after it was shaved off."
God doesn't care where we've been, what we've done, who we are. If we look to Him, He will help.
He doesn't think like people think. He doesn't write us off.
There is hope no matter what you've done. There is hope no matter where you are. Lean on Him. Trust Him. He'll get you to a better place.
