No I am speaking of the new nature that the born again child of God enjoys. This is the moral aspect of the Ten Commandments written on our hearts...those 10 are a reflection of His nature. The Sabbath command though is not a moral edict except that when we come to faith we are to rest in His Work.
For this is the covenant that I will make with the house of Israel after those days, declares the LORD: I will put my law within them, and I will write it on their hearts. And I will be their God, and they shall be my people. (Jer 31:33)
Instead of on stone, God's nature is now written on the believer's heart through His Holy Spirit....
And you show that you are a letter from Christ delivered by us, written not with ink but with the Spirit of the living God, not on tablets of stone but on tablets of human hearts.
Respectfully, can you give me a situation, in your church, that warrants treating a believer as an unbeliever?
