Eunice, a Godly mother.

She is not the most spoken about woman in the Bible and you probable don't remember hearing about her in Sunday school. None the less Eunice was used by God to help Timothy in his younger days.
The apostle Paul talks about her in his last letter to Timothy that he wrote in a dungeon in Rome, shortly before being executed for his faith.
He says "Recalling you tears, I long to see you, so that I may be filled with joy. I have been reminded of your sincere faith, which first lived in your grandmother Lois and in your mother Eunice and, I am persuaded, now lives in you also." 2 Timothy 4:6
The Bible says that sincere faith lived in Eunice (And her Mother, Lois). Eunice was married to a Greek man who most likely didn't share her love for God. Though she taught Timothy about Jesus Christ. Though it is not clear about how Timothy got saved, I would say that learning about the LORD as a child helped him.
I end with this, Eunice was a strong godly woman who loved God and helped her son!
