Mark 11:22 - belief from God

^.22And having answered Jesus says to them, "You must have belief of God.

God gives people His belief when He tells people what they should believe. We can rely on what God tells us concerning a specific situation or circumstance.

Once God communicates His belief to us, then we are given the opportunity to have the same belief regarding that specific situation or circumstance – by believing (having faith-in, trusting) the contents of what God says, His words to us. We should accept His belief being true to and for ourselves. God’s belief is not dependent upon whether a person believes it or not.

God communicates His belief to people in many different ways, for example: audibly for people to hear His voice speaking words, or God writes it down as He did for Moses in stone so people could read what He wrote, or via one of His angels speaking God's words, or via the spirit that God gives to His people which communicates the information to their minds, or via His previously revealed Word passed along from generation to generation by word of mouth or by writing it down, etc.

Once God reveals His belief to a person, then that person might tell others this belief so that they can hear it also.
