Personal vs. Private

A personal faith in Christ? Priceless.

A private faith in Christ? Worthless.

And Jesus came and said to them, "All authority in heaven and on earth has been given to me. Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the age." Matthew 28:18-20 (ESV)

So everyone who acknowledges me before men, I also will acknowledge before my Father who is in heaven, but whoever denies me before men, I also will deny before my Father who is in heaven.--Jesus, Matthew 10:32-33 (ESV)

C.S. Lewis on Social Morality

A Christian society is not going to arrive until most of us really want it: and we are not going to want it until we become fully Christian. I may repeat "Do as you would be done by" till I am black in the face, but I cannot really carry it out till I love my neighbour as myself: and I cannot learn to love my neighbor as myself till I learn to love God: and I cannot learn to love God except by learning to obey Him. And so, as I warned you, we are driven on to something more inward--driven on from social matters to religious matters. For the longest way round is the short way home.--C.S. Lewis in Mere Christianity
