It would be awfully nice to "know" that you're saved. A lot of Christians believe that you're saved if you accept Jesus Christ as your personal savior -- and in a sense that's true. If you REALLY accept Jesus Christ, and you live the way he told us to - shunning evils, loving the Lord, and loving the neighbor - then you're opening yourself to receive his love.
Covenant, Reciprocation, and Conjunction are three parts of the process of our spiritual rebirth.
The "as-of-self" is a key doctrinal concept in New Christian theology.
