Apostle Paul tells us to continue on in our good works, he tells us not to faint in our well doing, he tells us to have faith to believe and yet many of us faint in our adversity. We never consider the reason why our spiritual harvest is not coming to past. There are many reasons for poor spiritual harvest. It is just as important to know how NOT to do something as it is to know how to do it.
And it shall come to pass, IF thou shalt hearken diligently unto the voice of the Lord thy God, to observe and to do all His commandments which I command thee this day, that the Lord thy God will set thee on high above all nations of the earth. (Deuteronomy 28:1)
BUT it shall come to pass, if thou wilt not hearken unto the voice of the Lord thy God, to observe to do all His commandments and his statues which I command thee this day; that all these curses shall come upon thee, and overtake thee. (Deuteronomy 28:15)
Satan hath desired to have you, that he may sift you like wheat. (Luke 22:31)
