Can you imagine walking up to the gates of the White House and telling the security officer that you know the President and therefore he should let you in? Do you actually think the keeper of the gate would let you in? No! But what if the President came to the gate and said to the keeper: I know him, let him in! Do you think the gate keeper would permit entrance? Absolutely!
Here’s the point, it is not good enough to say you know the Lord. The Lord better know you!
