Occasionally I meet Christians who say “God is telling me to go and do this or that” and then the next minute God seems to have changed His mind. I remember one guy who made God look like He didn’t know how to make up His mind at all! One day it was “God wants me to do this.” and the next day it was something totally different. That’s not the unchangeable God I know and read about in the Bible.
Jesus chooses to teach some radical principles to His disciples up on the mountain.
Jesus spoke about Oaths and Swearing. He says in Matthew 5:33-37 (NLT) “You have also heard that our ancestors were told, ‘You must not break your vows; you must carry out the vows you make to the Lord.’ But I say, do not make any vows! Do not say, ‘By heaven!’ because heaven is God’s throne. And do not say, ‘By the earth!’ because the earth is His footstool. And do not say, ‘By Jerusalem!’ for Jerusalem is the city of the great King. Do not even say, ‘By my head!’ for you can’t turn one hair white or black. Just say a simple, ‘Yes, I will,’ or ‘No, I won’t.’ Anything beyond this is from the evil one.”
He says don’t go making promises and assurances that you may not be able to keep or being profane in your language by bringing God’s name into it. Just let your yes be yes. So let me get this straight - Don’t make promises but keep them anyway. Have the character to do the right thing anyway and speak in a way that is straightforward.
