How do you know someone loves you? They tell you. How do you know someone truly cares for you? They do things that show you.
Did you know God knows who really trusts in Him? Nahum 1:7 says, "The Lord is good, a refuge in times of trouble. He cares for those who trust in Him." Now, I've read this scripture many times in the past, but I have never seen the second part---God knows who trusts Him and who doesn't.
When you are around someone who doesn't like you or who doesn't agree with you, its pretty obvious, isn't it? Their attitude, body language, even facial expressions can give them away. So isn't it the same way with God? The Bible says He knows our heart and Nahum says God knows those who trust in Him. There is no hiding the truth.
Do you really trust God today? If we do our part, He promises to do His part.
