The foundation is Jesus. Paul explains how our works are judged and the outcome. The foundation is the key.
“According to the grace of God which was given to me, like a wise master builder I laid a foundation, and another is building on it. But each person must be careful how he builds on it. For no one can lay a foundation other than the one which is laid, which is Jesus Christ. Now if anyone builds on the foundation with gold, silver, precious stones, wood, hay, or straw, each one’s work will become evident; for the day will show it because it is to be revealed with fire, and the fire itself will test the quality of each one’s work. If anyone’s work which he has built on it remains, he will receive a reward. If anyone’s work is burned up, he will suffer loss; but he himself will be saved, yet only so as through fire.”

That's right and Jesus said
If you love Me,
keep My commandments John14:15
Jesus said to live by every Word that proceeds out of the mouth of God Mat4:4
Jesus who is God, before He became flesh said, written by the Holy Spirit of Truth:
Remember the Sabbath day to
keep it holy, the seventh day is the Sabbath
of the Lord thy God ,
the holy day
of the Lord Isa58:13 (never said this about any other day, but did say I am the Lord, I do not change Mal3:6 Heb13:8)
Building our house on the Word of God that comes with His power of Blessings Exo20:11 Isa59:2 and sanctification Gen2:3 Eze20:12 and His seal Exo20:11 Eze20:20 is building our house on Jesus John 1:1 because without His blessings and sanctification, we really are nothing Isa66:17 and no man can take away God's blessings or sanctification despite their objections to it, because they are not God.
God's Testimony Exo31:18 contained Ten Commandments Deut4:13 Exo34:28 and when we lay aside the commandment of God we make the Word of God of no effect Mat15:3-14 Mark7:7-13
God said Remember, man says forget. My Father wrote His Laws in my heart and by faith I am going to believe He did not forget the one commandment
He said Remember, that He said is holy and comes with His blessings that man cannot reverse Num23:20.
We are saved by grace through faith, the grace part is how we are saved, the faith part which is though our actions proves if our faith is genuine or not. Anyone can say Lord Lord, I believe Jesus is looking for more, to do His good will Mat7:21-23 Psa40:8 not to be saved, but that's how someone who is saved lives Rev14:12 which reconciles Rev22:14
By the way this is Jesus speaking on how to build our foundation on Him. not sure why you went to Paul instead when all he said is we build our foundation on Jesus, but Jesus tells us how to do that plainly. It was never left upon us to define, God defines, like He does everything else if one allows Him to.
Luke 6:46 “But why do you call Me ‘Lord, Lord,’ and not
do the things which I say? 47
Whoever comes to Me,
and hears My sayings and does them, I will show you whom he is like: 48
He is like a man building a house, who dug deep and laid the foundation on the rock. And when the flood arose, the stream beat vehemently against that house, and could not shake it, for it was [
j]founded on the rock. 49 But he who heard and did nothing is like a man who built a house on the earth without a foundation, against which the stream beat vehemently; and immediately it [
k]fell. And the ruin of that house was great.”
Guess we shall all find out soon enough. Time for me to move along.
