Mark 4:1-20 - Jesus introduces us to PARABLES here. It's a way to teach some truths to those who really WANT to hear. Our first question in this two-parter through the Parable of the Soils is, "Do you want to be productive in God's Kingdom?" and "How bad do you want to learn?"
God loves you and has sent His Son, Jesus Christ to pay the price for our sins. Why? Productivity for Him is one reason.
