1 Peter 1:16 for it is written: “Be holy, because I am holy.”

Hebrews 12:14 Make every effort to live in peace with all men and to be holy; without holiness no one will see the Lord.

God commands us to be holy. Holiness is a lifestyle. Holiness is doing whatever God told us to do in His word. The reason God commands us to be holy is, without holiness we cannot see God. If God tells us to “be something” that means He has already given us the ability to become it.
Notice, God doesn’t instruct us to be righteous because righteousness is freely given to those who accept Jesus as Lord and Savior (Romans 5:19). We can’t become something we already are.

For those who are living a an unholy lifestyle it’s time for a change. A person is literally playing with fire by living unholy.
Live Holy and See God.
