"But you, be strong and do not let your hands be weak, for your work shall be rewarded!” That verse came from 2 Chronicles 15:7 when the Lord told King Asa, through a prophet, that when Asa had opposition, he would win. God didn't want Asa to give up. He wanted Asa to have strength in Him when Asa was going to war against armies. God knew what Asa was up against, and that gave him the courage to go against the mountains that were coming against him. As long as Asa was following God, he was successful against his enemies. 2 Chronicles 15:2 says, "the Lord is with you while you are with him. If you seek him, he will be found by you, but if you forsake him, he will forsake you."
So, stay with God. Remain steadfast and strong in Him and don't give in to popular opinion or the latest and the greatest. Stay focused on what you're doing in the name of Jesus and no mountain or weapon formed against you shall ever come close to prospering. God has given you success. Continue to walk boldly in it.
