Luke 6:38 Give, and it shall be given unto you; good measure, pressed down, and shaken together, and running over, shall men give into your bosom. For with the same measure that ye mete withal it shall be measured to you again.
Matthew 10:8 Heal the sick, cleanse the lepers, raise the dead, cast out devils: freely ye have received, freely give.
It is not what was given that brings about the result but the FAITH behind the giving.
So, the one who gives with an understanding via faith will definitely be getting results than the one who gives under duress to satisfy the preacher.
2 Corinthians 9:7 Every man according as he purposeth in his heart, so let him give; not grudgingly, or of necessity: for God loveth a cheerful giver.
You can only give cheerfully (even in dire situations) through FAITH.
