"The sheep, which are mine, hear and hear my voice, and I know them, and they follow me" (John 10:27)
Many times we are not sure we can hear or recognize the voice of God and we fear in many cases, not being able to understand what the spirit of God wants to tell us.
Remember that the bible tells us: hearing the voice of the spirit is a privilege that every believer has (Romans 8:14) and Jesus also said "that his sheep recognize his voice and do not follow the voice of a stranger.
It is very important to know how to recognize the voice of God, and how we can obtain this privilege; having faith, meditating on the word and understanding it, as well as being obedient to what the word says, even in the most insignificant things.
