"Pursue peace with all men, and the sanctification without which no one will see the Lord." Hebrews 12:14
"Through Him then, let us continually offer up a sacrifice of praise to God, that is, the fruit off lips that give thanks to His name. And do not neglect doing good and sharing: for with such sacrifices God is pleased." Hebrews 13:15-16
If you admire someone, tell them. If you admire a trait about them or appreciate something they don't done tell them. It is okay to say this to someone else but it is so much more powerful to tell that person. That person very likely needs the encouragement.
We humans can get caught in our own worlds and forget to reach out. Reach out with your words. Reach out to encourage. Everyone needs some genuine love and encouragement from others. Everyone wants to know they are noticed, that they count, that they are appreciated. Please. Don't hesitate. Do this today.
