The Bible does not command that a practice of pledging must be followed. Pledging is, however, in the tradition and spirit of many examples in the Bible. A pledge or faith promise can be helpful in safeguarding our decision to return a portion of that with which God has blessed us. It can also remind us of the place that God has in our lives and keep the love of money from overcoming our love of God.
People are often hesitant to pledge a stated amount and for good reason.
Health, economic downturn, change in employment, can all effect a person s income over the course of a year. It is true, however, that every Christian can in good conscience make a faith promise to return a definite percentage of God s gifts to Him. She can always keep that promise.
