Psalm 145:8: The Lord is righteous in all his ways and loving in all his works.
How many times have you been shocked at how someone has acted simply because you have never seen them act in that manner before.
In many ways, the key to getting people to like or respect you is to make sure you are always consistent in the way you are with them - don't keep chopping and changing to match your mood!
People like consistency and they can object to change when it comes at an unexpected time - so try not to give them an opportunity to dislike the way you are... unless change is required!
God is consistent. God will always be the same. God has always been the same. We have grown to depend on that!
