How did Jesus teach the Greatest Commandment to his disciples?

In his latest book Reckless Love, author and Pastor Tom Berlin writes that Jesus taught them to love neighbor first as a way to more deeply love God.

In his exploration of Jesus' teaching and travels with his disciples, Berlin suggests that Jesus teaches us how to love God with heart, soul, mind, and strength by showing us how to love our neighbor. While many hope to learn to be better family, friends, leaders, and neighbors by finding a deeper relationship with God, what if becoming a better neighbor leads you to that deeper love of God?

In Reckless Love, you will consider your life, and learn how loving the people around you will completely renew your faith and give you a new experience of loving God. Additional components for a six-week study include a DVD featuring Tom Berlin and a comprehensive Leader Guide.
