"But just as he who called you is holy, so be holy in all you do; for it is written: 'Be holy, because I am holy.'" 1 Peter 1:15-16
There are some things that are humanly possible, and then there are some things that are NOT humanly possible. Sure, we can do some amazing things on our own. However, holiness is not something that we can achieve on our own. To be holy is to be perfectly pure, perfectly righteous, free and separate from evil. "Holy" is not a word that merely describes God. God sets the standard and the definition for the word "holy." As Christ followers, God has called us to be holy. Leviticus 11:44 says, "I am the Lord your God; consecrate yourselves and be holy, because I am holy." Again in Leviticus 19:2 we read, "Be holy because I, the Lord your God, am holy." And Peter repeats it again in 1 Peter 1:15-16. What does this mean for the Christ follower? If you look at 1 Peter 1:13-16 as a whole, you will see how we can strive for holiness: "Therefore, with minds that are alert and fully sober, set your hope on the grace to be brought to you when Jesus Christ is revolved at his coming. As obedient children, do not conform to the evil desires you had when you lived in ignorance. But just as he who called you is holy, so be holy in all you do; for it is written: 'Be holy, because I am holy.'" The only way for you and I as Christ followers to be holy is to put on the holiness of God through a personal relationship with Jesus Christ. The Holy Spirit indwells us as believers at the moment of our confession and belief in Christ, and God gives us new hearts and new minds. We become new creatures in Christ. Then we can do what Paul says in many of his letters to the early churches: We can put off the old self and put on the new self. We can have the mind of Christ as we live out our new lives. We can embrace the fruits of the Spirit as we leave behind the fruits of the flesh. As Christ followers and members of God's Church, we need to understand that holiness is not something we only strive for on Sundays. No, we strive for holiness in all that we do. Holiness should be a characteristic and a nature that Christ followers demonstrate each and every day, everywhere they go and with everyone they come in contact with. We can't do it on our own, but we don't have to. The Holy Spirit of God lives inside us, leading us and guiding us and powering us to be all the God created us to be. Remember what 1 John 4:4 says: "You, dear children, are from God and have overcome them, because the one who is in you is greater than the one who is in the world."
