In the Gospel today from Matthew 9, Jesus saw Matthew sitting at the custom post. He said to him "Follow me." And he got up and followed him.
First of all, how good it is to hear the voice of the Lord calling us! He calls because he loves us and needs us.
Secondly, he still calls us today. We may not actually hear him audibly, but he does speak to our hearts.
Any call from the Lord is to be welcomed, embraced, and treasured, for it's the highest of all calls, intended for his glory and our spiritual good. "If today you hear his voice, harden not your hearts."
