The one thing God cannot do

Is there anything God cannot do?

Yes, but only one thing. He cannot lie. (See 1 Sam 15:29 and Titus 1:2)

Meditate on this great truth from God's Word. This should enlarge your faith and confidence in Him, and shore up your convictions about His goodness and mercy. And then consider how Satan is building his crummy kingdom on a foundation of lies.

P.S. This is a great discussion topic for your next family meal.
