Mark 6:7,12 And he called to him the twelve, and began to send them out two by two, and gave them authority over the unclean spirits … So they went out and preached that men should repent.
There is a profound difference between what we want and what we need. The problem is, that we live in a world which spends all its time thinking about what we want, and little time learning what we need. What do I mean? Consider that there was a time before there was an Iowa lottery - if these days many dream of winning the lottery, and how it would change their lives, and how they could then get everything they want - what did people dream of before there was a lottery? In that time not so long ago, they dreamed of what they could do with the talents God had given them. Some dreamed of using their skills in sports, some dreamed of using their skills in music, some dreamed of using their skills in medicine, some dreamed of using their skills in business, some dreamed of using their skills in farming. And because we remembered that God had given us each skills, we also remembered that God would also give us each day whatever it is that we needed, and we were taught the scripture - with food and raiment therewith be content - and since we have always had much more than food for today, and the clothes that we wear - we have always had reason to give thanks and praise to God - and yet we have often forgotten this simple thing.
If we forget that God not only gives us the talents and abilities we have, as we;; as the opportunity to use them, it is easy to fall into not only unthankfulness, but into idolatry, for that is what it is, when we take the credit for what God has done. Idolatry blinds us, so that we may feel that something is not quite right - but we just don't know what it is - there is a nagging guilt, that doesn't go away no matter how hard we work, or how successful we become.
Everyone feels some degree of this guilt for a variety of things, things we have done, as well as things we have failed to do. And the message of the church has always been the same, and it always begins with, Repent! While we long to hear that God is love, and while we are greatly pleased that Jesus is our savior - if we don't know that we need a savior, if we are told that God is love, and God forgives all - without being told - repent! Then there is no reason why, having heard these things, we should feel compelled to tell anyone else.
Repent is not judgement - it is telling people that God has a plan for their lives, and that's why they feel bad, when they fail to live up to that law that God has written in the hearts of all.
And having called people to repent - then news of God sending his son to be our Savior is good news, because it is what we need, and it is when we needed it.
