The greatest block in the spiritual life is fear. Prayer, meditation, and education cannot come forth out of fear. God is perfect love, and as John the Evangelist writes, "Perfect love drives out fear" (1 John 4:18). Jesus' central message is that God loves us with an unconditional love and desires our love, free from all fear, in return.
For further reflection...
"Keep yourselves in God's love as you wait for the mercy of our Lord Jesus Christ to bring you to eternal life." - Jude 21 (NIV)
