Luke 6:46-49

Luke 6:46 (KJB)
And why call ye me, Lord, Lord, and do not the things which I say?

It is an absolute contradiction of terms to call Jesus Lord and then disobey Him. If one sees Jesus as Lord, then they must see Him as having absolute deity and authority and one who is to be obeyed without question. It is also the question of salvation that Jesus is preaching in contrast to the false gospel the scribes and Pharisees are preaching. If Jesus is teaching the truth and the people are calling Him Lord and then continuing on in the false religion of the Pharisees, then would purpose would it serve to call Him Lord? It would probably be only for show, just as external religion is.

Luke 6:47 (KJB)
Whosoever cometh to me, and heareth my sayings, and doeth them, I will show you to whom he is like:

Jesus then begins a parable concerning those who hear His sayings and doeth them. He then proceeds to show them what they can be likened to. There were probably many who were listening to Christ and were fence sitters, not knowing whether they should obey Him or stay with the old religion. The word “hearing” carries with it the meaning of “hearing with understanding.”

Luke 6:48 (KJB)
He is like a man which built an house, and digged deep, and laid the foundation on a rock: and when the flood arose, the stream beat vehemently upon that house, and could not shake it: for it was founded upon a rock.

It is one that has been saved and given spiritual ears to understand the spiritual things of the Lord. (Psa 94:22 KJV) But the LORD is my defence; and my God is the rock of my refuge. This person is likened to one who builds a house upon a rock. The rock being the Lord Jesus Christ Himself because He will be my refuge against Judgment Day since He will have paid for all my sins on Calvary. Any person in Christ is built on the rock.  Jesus now paints a picture for them of a very strong flood. The flood would point to the fact that flooding does take place in Palestine which causes the valleys to be filled and new channels would be created and then everything in its path would be swept away. The flooding represents the attacks of Satan against the true believer and no matter what he throws at them, they continue to stand strong in the midst of the flood or trials, just as Job did because Job like every other believer is founded on a rock. It can also represent the false doctrines which can cause an unsaved person to stray by following them. Those who try to gain Heaven by works are snared but the true believer will not be snared by them and thus the stream of deception would not touch them. The believer will not be touched by any evil scenario because they are firmly placed on the foundation of Christ. (1 Cor 3:11 KJV) For other foundation can no man lay than that is laid, which is Jesus Christ.

Luke 6:49 (KJB)
But he that heareth, and doeth not, is like a man that without a foundation built an house upon the earth; against which the stream did beat vehemently, and immediately it fell; and the ruin of that house was great.

Then Jesus contrasts the person who hears His words and acts on them with the foolish man who thinks that he can make it to Heaven on his own. It is like building a house on the sea shore but without a foundation and then when a flood comes, it does not take much of the torrents to take that house and have it come tumbling down. I think we all have seen what happens to a house in a path of a raging river. There is nothing left of the structure and that is the point that Jesus is making, that those who try and work for Heaven or who follow false teaching, will be completely consumed in the lake of fire, just as a house is in a major flood. (Mat 10:28 KJV) And fear not them which kill the body, but are not able to kill the soul: but rather fear him which is able to destroy both soul and body in hell.

Then the same intense flood which hit the house that was built on the rock now hits the house built on the sand. The difference is that all the attacks which could be mustered by the kingdom of Satan has a different effect on this person. They believe they can get to Heaven by works and they follow false teachings because they are palatable. The result of all the satanic attacks is that in the end, they will fall in ruins. False teachings and works gospels will have their reward of eternal damnation. This is why Jesus states that when they fell, the fall was great because there is no greater fall for man than eternal punishment in the lake of fire. The Greek word for “it fell” can also be understood as “collapsed.” So the result of following false gospels is not a light thing but one of eternal consequences. Without being on the foundation which is Christ, there will be no chance of surviving Judgment Day and getting into Heaven.
