If we follow God’s Word, we will prosper  -  1 Chronicles 22:13

Then shalt thou prosper, if thou takest heed to fulfil the statutes and judgments which the LORD charged Moses with concerning Israel: be strong, and of good courage; dread not, nor be dismayed.

This is a conditional promise that will never change. If we want to prosper, we must follow the commandments, decrees, and principles in God’s Word.
