The following Scriptures from the Bible will show you that: Jesus is the Foundation- on which we must build our House (our understanding).
Psalm 61:2 - From the end of the earth will I cry unto thee, when my heart is overwhelmed: lead me to THE ROCK that is Higher than I.
Psalm 62:2 - He Only is MY ROCK and my salvation; He is my defense; I shall not be greatly moved.
Psalm 127:1 - Except The LORD build The House, they labour in vain that build it: except The Lord keep the city, the watchman waketh but in vain.
Psalm 147:5 - Great is Our Lord, and of Great Power: His Understanding is Infinite.
Luke 6:47-48 - Whosoever cometh to Me, and Heareth MY SAYINGS, and DOETH THEM, I will show 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.
I Corinthians 3:11 - For other foundation can no man lay than that is laid, which is Jesus Christ.
I John 5:20 - And we know that the Son of God is come, and hath given us an Understanding, that we may Know Him that is True, and WE ARE IN HIM THAT IS TRUE, EVEN IN HIS SON JESUS CHRIST. This is the True God, and Eternal Life.
SO you see, the Sayings of Jesus is the foundation, or the Rock that we must build our understanding upon.
What are The Sayings of Jesus?
"Love one another"
"Forgive one another"
"Bear one another's burdens"
"Do not Judge nor condemn"
"Bless those that use you and persecute you"
"Turn the other cheek"
"Believe and have Faith"
And many more wonderful Truths. These are the Truths that build a sure foundation, and no confusion can destroy this understanding (house).
Jesus is the Rock of Ages.
