Making excuses. This person always has a reason or explanation why it really isn't true or isn't their fault.
Proverbs 13:10 (KJV) “Pride only breeds quarrels, but wisdom is found in those who take advice.”
Isaiah 13:11 (KJV) “I will punish the world for its evil, the wicked for their sins. I will put an end to the arrogance of the haughty and will humble the pride of the ruthless.”
Often times, when the Lord ask us to do something, we give excuses why we cannot do it. We sometimes forget that whenever He gives us an assignment, he always provide the enablement. A great read on the subject would be found in Exodus chapters 3&4 on the life of Moses. Five times Moses gave excuses to God why he would not be able to lead the Israelites out of Egypt to the Promised Land and five times God assured and proved to him He would help him.
When we tell God we can’t—do what He says we can, we call God a liar. Another way to put this is to say, “I know more than God.”
