Our relationship with God is driven by the Grace Construct. No one was created to arrange a relationship with God without the revelation of God's grace. It's simply impossible. The idea of this construct as it was given, was to guide and govern our relationship with Jesus from start to fullness. Notice that we did not say from "start to finish"  because our relationship with God never comes to an end. Instead, it comes to fullness when we see Jesus face to face. 

If your relationship with God is going to stand on solid grounds, then you'd have to be introduced to the construct of God's grace. You will struggle to enjoy fellowship with Jesus without an understanding of this construct. You will even struggle with fellowship with Jesus without an in-depth revelation about the construct of Grace.
