God is not interested in how high you can jump, but God is more interested in how straight you walk. We have more of the world in the church than the church in the world because of a lack of spiritual holiness from God.
1 Peter 1:16 says, "Be holy, for I am holy." If you were to look up the original meaning for the word "holy," you would find that it means to be separate, set apart, and be reserved for a particular purpose." As Christian, that is what we should all be doing.
Everything we do with our mouths, money, and morals belongs to God. Therefore everything we say, we do, and we drink, we read, where we go, and who we associate with should be done with holiness in mind. As children of God, we should be conformed to the character of our heavenly Father, not to this world.
1 Peter 1:14-15, "As obedient children, not fashioning yourselves according to the former lusts in your ignorance: But as he which hath called you is holy, so be ye holy in the manner of conversation."
