Then Jesus came to them and said,
"All authority in heaven and on earth has been given to me.
Therefore go and make disciples of all nations,
baptizing them in the name of the Father and of the Son and of the Holy Spirit,
and teaching them to obey everything I have commanded you.
And surely I am with you always, to the very end of the age."
(Matthew 28:18-20 NIV)
The toughest part about this "lukewarm" discussion is that most of it centers around our personal holiness. While that's all well and good, that is only the precursor to what Jesus want's us to accomplish.
He didn't command us to go into all the world and avoid sexual immorality. He didn't command us to go into all the world and make people tithe. He commanded us to go make disciples of all nations - fully devoted, teaching-following disciples. Our Commander and Chief told us to bring people to Him, baptize them in Him, and teach them to obey Him. Those are our marching orders.
I grow weary watching how our society has convinced believers that they "can't" discuss God or religion in our schools, our workplaces, or, for that matter, in polite company. It simply isn't done. At the same time, we forget that we can't not discuss it. We've been told to discuss it. We've been commanded to discuss it. We are given the mission to discuss it.
As it is, you boast in your arrogant schemes. All such boasting is evil. If anyone, then, knows the good they ought to do and doesn't do it, it is sin for them. (James 4:16-17 NIV)
The woman at the well brought streams of people out to hear Jesus. Matthew (Levi) threw a party so his "sinner" friends would meet Jesus. We are implored by God to share with our spouse, children, parents, friends, neighbors, and enemies. Sharing God is not an option. It's not for the "mature" Christian. It's for all of us. No holding back.
