Deuteronomy 30:9
And the LORD thy God will make thee plenteous in every work of thine hand, in the fruit of thy body, and in the fruit of thy cattle, and in the fruit of thy land, for good: for the LORD will again rejoice over thee for good, as he rejoiced over thy fathers:
The promise was first given to Israel after they had chosen to serve God, and it stands as God's word to backsliders in 1897 to return to Him without delay. Its fulfillment is conditional on returning and obeying the voice of the Lord, doing all His commandments, keeping His commandments and statutes written in the book of the law, and turning to the Lord their God with all the heart and with all the soul. To those who turn wholeheartedly in that way, He will make them plenteous for good in every work of their hand, in the fruit of the body in children, in the fruit of cattle in livestock, and in the fruit of the land, and He will again rejoice over them for good as He rejoiced over their fathers.
In its wider setting through verse 20 the passage lays down principles plainly defined by God Himself, requiring justice and mercy and love for God and for man while expressly forbidding the opposite. Those principles are binding upon His people who are called by His name, and especially upon men in responsible positions at the heart of the work. When such men take up the truth without conversion of heart, mingle their own spirit with their counsel, and combine together to do the very things God has forbidden, they walk contrary to God. In doing so they pervert principle, insult God, abuse His honor, and misrepresent His character, until justice and mercy and love fall in the streets and equity cannot enter.
