Holiness is a bit of a scary word for Christians: it’s pretty loaded. But it shouldn’t be so scary or seem as “far away” as it may seem.
Holiness isn’t about being some sort of thing in a museum, something that your parents told you not to touch or you’d be in trouble. It’s not being all “special.”
You don’t become holy by trying to be holy. You become holy by losing yourself, by giving your life so that you can love others and serve others, serving God! Holiness is being a servant, by seeing yourself as the least of everyone. So stop thinking about yourself and you’ll be that much closer to God.
“Whoever wishes to come after me must deny himself, take up his cross, and follow me. For whoever wishes to save his life will lose it, but whoever loses his life for my sake will find it.” – Matthew 16:24-25
