"Of Him all the prophets bear witness that through His name everyone who believes in Him receives forgiveness of sins."
Have there been times in your life when you met someone and your just felt very comfortable, that there was no threatening environment? Well this is your spirit bearing witness with another. I have also been in a situation when I felt every hair stand up on the back of my neck, I knew that his spirit did not bear witness with mine. It's not a good feeling. This is just scripture coming to life, giving us reassurance that God is just Who He says He is! It's awesome as His child to know that God gives us red flags to know how we should proceed in certain situations. So next time you meet someone and you know that there is something very weird about them, think back to this scripture. It could be God telling you just what is different about them. And also remember that this is your opportunity to share Jesus with them.
