But one point is in agreement (with me at least!) there is no salvation unless there is belief and following in Jesus. Remember, noone comes to the Father except through Jesus.
I'm in total agreement with you!
Concerning commandments, yes, we are to follow them as best as we can. As I'm sure you've learned, when we don't, our lives can/will become much less enjoyable from the chastisement of the Holy Spirit and the built-in curse that goes along with each different sin.
I believe that if all believers would keep the Great Commandment, "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. (Mark 12:30)," that all of the other commandments would fall into place.
