To another He said, "Follow me." but he said, "Let me first go bury my father." But Jesus said to him, "Let the dead bury their own dead; but as for you, go and proclaim the kingdom of God." Matthew 8:22, Luke 9:60
This mark is one reason why the road to immortality is the one less traveled. Even goody-goody two-shoes would have a tough time walking away from her father, especially if he needed burying, especially to run off with another man. It takes more than being good to become immortal.
Jesus Christ shined the spotlight on this mark when He said things like, "Those who leave brother and sister and father and mother for my sake will be rewarded in the kingdom of heaven," and "If you don't love Me more than your family, then you are not worthy of Me." Allegiance to the immortal Trinitarian God must be pure and exclusive. Nothing less will do. Remember: it's God. Love your family, but be willing to disconnect from them to serve God.
When John the Baptist, and later Jesus proclaimed that we must Repent, they simply meant that we need to stop shooting arrows into the air with our behavior, our choices, and even our attitudes. Hit the mark. Repent! Be penitent again and again and again to get it right. Be sorry for not even trying to hit the mark; be sorry for trying and missing the mark, and try again. Do it!
Follow the Leader; talk up the kingdom of God and how different that is than all the unUnited Nations of this world. ‘Let the dead bury their own dead’ is not a nice thing to say. This mark chooses life over warm fuzziness, dinner before dessert.
