Purity

Create in me a pure heart, O God, and renew a steadfast spirit within me.
Psalm 51:10
I ask God to do the same for me.
Purity is not just related to refraining from sexual immorality. It's also about being pure in HEART.
“Your eye is like a lamp that provides light for your body. When your eye is healthy, your whole body is filled with light. But when it is unhealthy, your body is filled with darkness. 35 Make sure that the light you think you have is not actually darkness. 36 If you are filled with light, with no dark corners, then your whole life will be radiant, as though a floodlight were filling you with light.” Luke 11:34-36
Your eyes literally absorbs everything you see and listen to into your body. If you watch a horror movie, you're allowing the dark spirits into your body. If you talk with someone who gossips and hates people, you're inviting the spirit of bitterness in. If you're reading a book about witchcraft, you're inviting spirit of witchcraft in. If you're watching a dirty TV show, you're inviting spirit of lust in. These spirits can cause depression, anxiety, suicidal thoughts, unwanted sexual desires, and so much more. I can go on and on about this. The spiritual realm is SO REAL. What you do spiritually LITERALLY affects you.
Make sure what goes in your eyes is good. Meaning...
1) Movies/TV shows (avoid horror movies, dirty shows, shows that mock God)
2) Pictures
3) What you read, on your phone and books
4) All of your conversations with people. If they feed you negativity, refrain from them. If they feed you God's words of life, stay with them.
5) Events and places
Blessed are the pure in heart,
for they will see God. Matthew 5:8
I'm telling you, the more pure you become in your heart, the more blessed you will be. You WILL literally experience God.
