Whatever a person believes about being accountable to God is how he will live this life.  If we tell ourselves half-truths or false narratives we will soon believe them, which will form what is important or of value to us as to what we think we need, or will make us fulfilled. Soon we will develop convictions about how to secure or accomplish whatever we believe to be true about us. All of this is reinforced by our emotions into our life's motivation or trigger points.  This is why knowing the truth about life and man and God are essential to having a healthy lifestyle.
