This attitude toward God finds expression in one's attitude toward others, often causing people to have a low estimate of the ability and worth of others and therefore to treat them with either contempt or cruelty. Presumption and pride may be considered to be the root and essence of sin. Perhaps it is sin in its final form. In either case, it is a grievous sin. They blame others and excuse themselves.
Presumption refers primarily to the attitude of one's heart.
It emphasizes the plight of the one who has been blinded by presumption. Presumption may appear in many forms. Some of the more common are pride of race, and spiritual pride. For such are false apostles, deceitful workers, transforming themselves into the apostles of Christ. Just begin speaking of your love for the Jew.
