You are a cult!
Empty Grace is a cult.
Dispensationalism is a mega cult!
Put the two together and Matthew 7:23 just jumps out glowing bright red.

The law was fulfilled in Christ on our behalf. Here are the words of Jesus concerning the law.
Mark 12:29 And Jesus answered him, The first of all the commandments is, Hear, O Israel; The Lord our God is one Lord: 30 And thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength: this is the first commandment. 31 And the second is like, namely this, Thou shalt love thy neighbour as thyself. There is none other commandment greater than these.
Then we have these words to know who actually knows God.
1 John 4:7 Beloved, let us love one another: for love is of God; and every one that loveth is born of God, and knoweth God. 8 He that loveth not knoweth not God; for God is love.
I would contend that from your vitriolic words in these threads to others and your obvious disdain for those who call themselves Christians you do not know God.
