Worldly things can be misinterpreted to what we see, but things of the world are those that affects your spiritual being. 1 John 2:15 Do not love the world or the things in the world. If anyone loves the world, the love of the Father is not in him.
Conforming to things of the world, is about what impacts the spirit in a man. You cannot look ugly because you are afraid that people will say you are conforming to the world. Before Esther appeared to her husband to be, she spend a good time with beuticians, so she look best before him. Esther 2:9 Now the young woman pleased him, and she obtained his favor; so he readily gave beauty preparations to her, besides her allowance. Then seven choice maidservants were provided for her from the king’s palace, and he moved her and her maidservants to the best place in the house of the women.
Others think you cannot be a christian and be involved in politics. we need christians to go into politics so they can influence decisions towards a godly life.
