I don't get grace

Grace is God's ultimate gift to us. It is unmerited favor from God given to people who don't deserve it. It is often described in Christianese with the backronym "God's Riches At Christ's Expense." It is by His grace, we are saved. So I get that part.

So here's what I don't get... why me and not someone else? Certainly there are people who have done more good and/or less bad that don't know His grace. Why did I win the "eternity lottery" and others won't? Most of all, why did God (in all His righteousness) decide to save even one of us (in all our wretchedness)? Ephesians 4:7 says, "But to each one of us grace was given according to the measure of Christ’s gift."

The measure of Christ's gift... think about that. Christ's gift was God Himself, creator of all things, leaving heaven and coming to earth, living life as a human (and showing us how it's done, in the process) then submitting to the authority of this world and dying a horrible, painful, wicked death- being tortured and teased and left hanging on a tree. That is the measure of Christ's gift, and the bible says that each of us received grace according to the measure of that gift. I don't get it.

As a teacher in the church, I seem to think often that my greatest goal should be life change for the people in our church. But it's not. See, for me to change someone's life, I need to teach that grace is not enough. You need to have grace and give your tithe. You need grace and to serve. You need grace plus a good life. But, grace plus anything denigrates the measure of Christ's gift. Christ's body was broken for you. His blood was spilled for you. As he hung on the cross, your picture went through His mind. That plus nothing is enough for anyone.
