When God has specially promised the thing we are bound to believe we shall recieve it when we pray for it. You have no right to put in an if and say Lord if it be thy will... This is to insult God. To put an if in Gods promise when God has put none there is tantamount to charging God with being insincere.
Have you ever noticed how when youre happy time seems to pass by fast while when youre miserable it goes real slow Life would have been a blink with you whether it lasted a millennium or a month.
