David's heart

"Now it came to pass, when David was dwelling in his house, that David said to Nathan the prophet, 'see now, I dwell in a house of cedar, but the ark of the covenant of the Lord is under tent curtains.'” 1 Chronicles 17.1

 David committed sins that were not erased. Violent and unjustifiable sins. He  and his people reaped its fruits. However, even in the face of such outrage, his heart remained according to God's heart. The above verse proves that, for in his concern with the building of the House of the Lord, he considered his faith and covenant to the God of his forefathers.

Prudent

“Therefore whoever hears these sayings of Mine, and does them, I will liken him to a wise man who built his house on the rock: and the rain descended, the floods came, and the winds blew and beat on that house; and it did not fall, for it was founded on the rock." Matthew 7.24-25

Building a house on the rock requires more time, money and overall effort. However, once ready, nor even tsunamis are not able to bring it down.
The same applies to one who builds his life on Jesus. That is, listening and practicing His Word.

MONEY CANNOT BUY

"Many waters cannot quench love, nor can the floods drown it. If a man would give for love all the wealth of his house, it would be utterly despised."
     Songs 8.7

Even if a man gave all of his wealth in exchange for love, it would not be enough. There is nothing in this world that can be exchanged for true love...
Only the Holy Spirit can guide us in the direction of pure and sincere love because He is love.
Therefore, those who want to love and be loved must first seek and receive the Spirit of love. 

WALK IN THE SPIRIT

"I say then: Walk in the Spirit, and you shall not fulfill the lust of the flesh."    Galatians 5:16

How is it possible to be in a pit and walk in the Spirit?
Walking in the Spirit means that your mind is occupied with the Word of God throughout your day. 
When your thoughts are focused on the Almighty, it is impossible to fall into temptation because the Spirit of the Word sustains, supports and strengthens the faith.
