And why call ye Me, Lord, Lord, and do not the things which I say? Whosoever cometh to Me, and heareth My sayings, and doeth them, I will shew you to whom he is like: 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. 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. Luke 6:46-49
Jesus is speaking of two different hearts. Everyone who says, “Lord, Lord” will not enter His kingdom (Matthew 7:21). Just because one professes “Jesus is Lord” does not make it so.
Doing what He says is the fruit of our confession of Jesus. Believing Him and doing is the work of God which brings forth fruit of salvation, and Jesus is Lord of one’s life.
The one who lays the foundation of faith in Him, plus nothing, minus nothing, will have the faith that stands the test and trials of every storm, wind and rain, and flood.
If we say “Jesus is Lord” then let us build on that foundation (1 Corinthians 3:11). He is the exclusive way, the only way to God the Father, eternal life, peace and joy (John 14:6; Acts 4:12).
