Episode Details

Jesus constantly used the language of "entering" the kingdom. It's possible to be outside, and then to get inside.

We enter through faith; the moment when someone places their confidence in Jesus is their entrance into the kingdom of God. 

At the same time, it's just the *first* moment of a whole life of discipleship to Jesus that is beginning to unfold. Dallas Willard once said, "Discipleship is a natural part of confidence in Jesus as he really is."

When Jesus frees us, our response is to follow him. As Charles Wesley wrote in the hymn "And Can It Be":

My chains fell off, my heart was free;
I rose, went forth, and followed Thee.
