Jesus told Peter to walk on water. Do Christians get together and walk on water?It has nothing to do with Christianity, except it was Christ who those parables. It has everything to do with Christianity.
"Joy" -- You think being a Christian is about your Joy?
Why would anyone think that something Jesus said has nothing to do with Christianity?
Everything Jesus said was ''prior'' to the cross. The OT and the gospels need to be read by looking 'through' the cross.
A Christian ''has'' dedicated their ''all'' to God. That is why they have received faith from God to believe a man who walked the earth 2000 years ago is in fact Lord, God of the universe.
We have gone from worker to bride. No / old covenant to new covenant. Not grafted in, to grafted in. Gentile, to child of God. A worker is dismissed if they do not do their work. Imagine telling your wife, ''honey, I want a divorce as you did not do the ironing. I throw out the wicked and lazy... servant'' Cough cough.
