The document discusses how God demands holiness, obedience, and the heart from believers. It provides biblical examples to support each point. For holiness, God demands it but supplies his grace. For obedience, Abraham's willingness to sacrifice Isaac is given as the prime example of obeying God even when it is difficult. God rewards obedience with blessings. For the heart, God demands love and looks at the heart rather than outward appearances. God supplies his love in return for a heart devoted to him.
