"A double minded man is unstable in all his ways." James 1:8
When you know you have heard from the Lord on a particular matter, don't get double minded and start wavering. I said, "When you KNOW you have heard from the Lord". I didn't say when you think or assume you have heard from Him but when you know beyond a shadow of a doubt, when the word is like bedrock in your spirit, when you have no doubt you have heard, then don't allow doubt to come in.
When Jesus told Martha that He was going to raise her brother Lazarus back to life, she believed. But when Jesus told them to roll the stone away, she began to waver and doubt because of her sense of "smell". He had been dead for four days so naturally his body would stink. She believed Jesus' words but her natural senses were making her waver.
Again, if you know that you have a true word from the Lord and not just a "hope-so" word, don't let your natural senses convince you otherwise. Don't look at the situation and believe what your eyes tell you. Don't listen to the negative and believe what your ears tell you. Don't let your feelings cause you to believe what they are saying-- it is impossible, it can't happen, it isn't logical, etc. Our faith and hope is in what the Lord said alone, not what our senses say.
Have a great day. Don't let your feelings and natural senses make you believe contrary to what the Lord has truly spoken to you.
