Seven
Lucky number seven...seven days in a week...seven deadly sins- you get the picture. Seven is an important number in the Bible too. Seven is the number of God is considered the number of perfection. Through out the Bible it seems that God works in sevens, perhaps to remind us of his control of everything. He created everything in six days and on the seventh day he rested. Jesus Christ fed a multitude of people with seven loaves of bread.

Jesus used the number seven in reference to forgiveness (see Forgiveness). One of his disciples asked how many times he should forgive someone, asking if seven times was enough. Jesus corrected him, saying that he should always forgive, no matter how many times he had been wronged- not only seven times, but seventy-seven times (see Matthew 18:22).

After spending six days creating the earth (see Creation), God rested on the seventh day. Likewise, he commands us to take one day out of the week to rest (see Rest).
