1 John 2:4
If someone claims, “I know God,” but doesn’t obey God’s commandments, that person is a liar and is not living in the truth.
There is a responsibility and a sense of expectation that comes with knowing God. If you claim to know God there are certain things that are expected of you. You are expected to speak differently, act different, respond differently, have different standards and so forth. It is simple, you are expected to resemble the one whom you claim to know, and follow.
Your actions and everything else are expected to be a reflection of Him.
If you claim to know Him the you are required to grow in Him, because those who truly know Him spend time with Him and out of that relationship they build the grow beyond what they themselves can imagine. Claiming to know Him puts a different set of requirements on your life, because If you say know Him the world expects there to be a difference between you and it.
Laying these claims requires you to obey His commands. However you cannot obey His commandments if you do not know the word. Therefore you must find rest start with knowing His word so that through that knowledge and insight you know what His commands are. Knowing Him is not just a fancy claim we get to lay, but rather it’s a lifestyle we ought to live. So if you are claiming Him let it be very evident in your lifestyle.
