Hebrews 4:12 (New Living Translation)
12 For the word of God is alive and powerful. It is sharper than the sharpest two-edged sword, cutting between soul and spirit, between joint and marrow. It exposes our innermost thoughts and desires.
This verse is very true. When you read the bible, the messages can really relate to life. I really dig the King James Version of the verse.
Hebrews 4:12 (King James Version)
12For the word of God is quick, and powerful, and sharper than any two-edged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart.
This verse I think would be good if you want to be a missionary. Even when you speak to an Atheist about God, the word of God speaks in ways you cannot. That is God doing his magic. People can have there whole lives changed.
You don’t even have to spout verses at people to do God’s work. You can pray for them. That’s what I try to do, even if the person is being a jerk.
