For Muslims, man is the high point of God's creation. Religious activity such as ritual prayer, pilgrimages, alms giving, fasting and reciting the Muslim confession of faith are at the heart of Islamic religious experience. But for Christians, sin is not simply a matter of making mistakes, but rather of living in opposition to Godly character.
Muslims need to know that there are treasures within the Bible, our personal sharing with Muslims are dynamic events involving interaction. Psalm 19 is a good choice. I point out that this is the "Zabur" (Psalms) mentioned in the Qur'an.
It is certain that these last five years has seen the Muslim world groaning in great pain. Wars, earthquakes, tsunamis, daily struggles with poverty, lose of family members plus an emptiness of spirit and soul are things we need to think and pray about for Muslim peoples.
