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 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 on a rock. - Luke 6:46-48

    Notice that our Lord likened the wise man (Mt. 7:24) who built His house upon the rock (the Lord Jesus Christ Himself) to one who “digged deep.”  But also note that the reason the house withstood the storm was not because of the digging, but rather because of the foundation that was unearthed – “for it was founded upon a rock.”  It’s not the digging deep that makes the difference, yet all whom God justified by the blood of Christ and who shall so stand at the judgment, will ultimately be drawn by God’s irresistible grace in their respective lifetimes to persist in seeking (or digging) until they find.  In the day of His power, God reveals to them that one foundation, “a tried stone” who produced the very righteousness necessary and satisfactory to the judgment of God, a “sure foundation” (Isa. 28:16), the Lord Jesus Christ.  Sinners are commanded to “strive to enter in the strait gate” (Lk. 13:24), to dig deep so to speak in seeking “the kingdom of God and His righteousness” (Mt 6:33).  And all for whom Christ lived and died shall do just that.  All that the Father giveth Him shall come to Him (Jn 6:37) – to Christ, the solid rock!
