Grace was preached in the Amish churches, albeit different from what we now view grace to be.
So just what did we believe while we were Amish?
We believed Jesus was the Son of God and that He came to die in order to open the gates of heaven for all those who live a righteous life. We believed He was our perfect example on how to live life. Sunday after Sunday the preachers preached about grace, we will need it on judgement day they explained again and again. I can still hear them, "When we stand before God on judgement day and we step on the scales to see if we have lived a good enough life, if we did our best but still come up a little short that is when grace kicks in and Jesus will step up, put His foot on the scale, and we will be worthy of heaven."
Grace doesn't look like a last resort to us any longer. It's everything. Jesus paid it all, without Him we are nothing. At judgement day I want to be standing before God clothed in His righteousness.
