In most cases we talk to God alot and ignore hearing from him and so we can never know what to do next especially when the situation involves a decision to take. We usually expect God to manifest to us in the so called splendous ways. Elijah at a time when he was hiding away from Jezebel witnessed different forms that we usually want God to reveal himself to us. He felt a very strong wind, an earthquake, fire but God wasn't in any of them. Of recent I have realised God speaks to us through the small still voice which is the holyspirit. It feels like an instict in us telling us to do something. Your conscience will always help you know whether it is from God or the devil. God always shows us a sign to prove his word and promises to us.
God speaks to us through the written word and that's the bible. Romans 12 says be ye transformed by the renewing of your mind that you may know the good,acceptable and perfect will of God. We have to judge situations in reference to the word of God.God also does speak to us through dreams. So never take dreams for granted. Always pray and cancel any bad dreams immediately you wake up.We must have a secret time with God in order to hear from him. Psalms 91:1 says he who dwells in the secret place of the most high shall abide under the shadow of the almighty.
