Dwelling in the house of the Lord forever

Psalm 23:1-6
The Lord is my shepherd, I shall not be in want.
He make me lie down in green pastures, he leads me beside quiet waters.
He restore my soul. He guide me in paths of righteousness for his name's sake.
Even though I walk through the valley of the shadow of death, I will fear not evil, for you are with me; your rod and your staff, they comfort me.
You prepare a table before me in the presence of my enemies. You anoint me head with oil; my cup overflows.
Surely goodness and love will follow me all the days of my life, and I will dwell in the house of the Lord forever.
This best-known, best-loved of all psalms pictures God, the Good Shepherd. He provides all that his people need.
He leads them through life. He secures them from all harm.
Verse 5 introduces a second picture: God, the perfect host, feasting his people with good things, And it goes further: because 'in the Old Testament world, to eat and drink at someone's table created a bond of loyalty' the picture is not simply of a guest but of a friend.
Why?
The Lord is my shepherd, he will provide me everything I need, God loves me.
God make me rest and peace and comfort my soul.
God's training, guidance and punishment comfort me and turn me on the right way.
God's protection is full so I won't shaken and fear.
Deepest darkness has generally been taken to mean death: hence 'vally of the shadow of death'
How?
How great is one who belong to the Lord, dwelling in the house of God forever.
