Faith is to believe. The bible has recorded God�s many promises. Concerning the promises, only those who truly believe without doubting shall attain. As for the unbelieving, they will have no share of the promises. Hence, a believer�s faith is the key that opens the door to God�s promises. We must not fret nor doubt but to stand on the promises of God and wait patiently. Let God decide the opportune time to fulfill his promises. Regardless of how long the waiting period, we must believe earnestly that the faithful God regards his pledges seriously. For his every promise is based on his righteousness and faithfulness. He will surely not default on, overlook or alter his promises. He is a God who works continuously in the secret, altogether trustworthy and without deception. In times past, many steadfast and enduring believers have personally experienced his wonderful and timely fulfilling which never failed due to lateness. However, some promises cannot be attained by faith and endurance only, one must first do his will to obtain them. This doing his will is something that we must not be ignorant of, otherwise, we give ground to Satan to cause us to doubt his promises to the extend of having out faith shaken. Someone ever faith that doubting and worrying, being discouraged and frustrated are types of arrows that Satan target at believers� mind, so as to cause God�s people to fall from grace and fail to live up to a good testimony glorifying God. Against such treacheries believers must be on guard.
