Do not conform to the pattern of this world, but be transformed by the renewing of your mind. Then you will be able to test and approve what God’s will is – His good, pleasing and perfect will.
In order to hear from God we need to have our mind changed to be receptive to what God wants to say. The bible clearly teaches us that we are to change our way of thinking and that we need to do that in order to be able to test and approve what God's will is God speaks to us through our minds but our minds are distorted, sinful, therefore we need to have our minds changed such that we are ready to hear God's will. Then, when there was a crisis when we desperately need to hear from God, we will be ready to hear it and understand what God has to say. Change your mind then by regular attention to God by regular reading of his word in scripture and regular asking to be filled by God's spirit committing yourself to learn as he teaches you and changes you. That is the way that you can rely on hearing from God when you really need it.
