John 6:44 No man can come to me, except the Father which hath sent me draw him: and I will raise him up at the last day.

Which means people can only understand what Jesus TAUGHT if the Father 'allows' it.

Others are like this mentioned below.

Matthew 15:7-9 Ye hypocrites, well did Esaias prophesy of you, saying, This people draweth nigh unto me with their mouth, and honoureth me with their lips; but their heart is far from me.
But in vain they do worship me, teaching for doctrines the commandments of men.

All Lord, Lord this, and God, God that. Jesus is this, Jesus is that.

Matthew 7:21-23 Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven. Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works? And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.

Good luck doing his will if you ignore him.
