He said 'Who are You, Lord?' Acts 9:5
One of my favorite books of the Bible is Acts.
I recently was telling my daughter the story of Saul, and how he became Paul after becoming blind and encountering God.
I like Paul's self doubt on God using him to spread the Gospel across the world.
God didn't force Paul to serve. He allowed Paul to choose, and becasue he choose of his own free will, he became one of the greatest teachers of the gospel.
Likewise we have a choice to follow and obey. God doesn't want me to obey and follow Him because I HAVE to, he'd rather it be because I WANT to.
Being forced to is religion.
Wanting to is a relationship.
