Bottom line: Samson was strengthened by God even though he was sinful because he was willing to be faithful.
I am Samson. I am like Samson. I am no superhero. I can be used of God.
I have a story like Samson. God brought me into this world on purpose with a purpose.
I have the same source of strength like Samson. God's Holy Spirit strengthens me to serve His calling.
I, too often, have sin like Samson. When I yield to my fleshly desires, I will be led to sin.
And yet God will use me and strengthen me (a weak sinner) if I will be willing to be faithful.
