As the Scriptures have said

John 7:37–39 ESV

On the last day of the feast, the great day, Jesus stood up and cried out, “If anyone thirsts, let him come to me and drink. Whoever believes in me, as the Scripture has said, ‘Out of his heart will flow rivers of living water.’ ” Now this he said about the Spirit, whom those who believed in him were to receive, for as yet the Spirit had not been given, because Jesus was not yet glorified.

Psalm 18:1–6 (ESV)

I love you, O Lord, my strength.

The Lord is my rock and my fortress and my deliverer,

my God, my rock, in whom I take refuge,

my shield, and the horn of my salvation, my stronghold.

I call upon the Lord, who is worthy to be praised,

and I am saved from my enemies.

The cords of death encompassed me;

the torrents of destruction assailed me;

the cords of Sheol entangled me;

the snares of death confronted me.

In my distress I called upon the Lord;

to my God I cried for help.

From his temple he heard my voice,

and my cry to him reached his ears.

Hebrews 11:6 ESV

And without faith it is impossible to please him, for whoever would draw near to God must believe that he exists and that he rewards those who seek him.

Exodus 17:6 ESV

Behold, I will stand before you there on the rock at Horeb, and you shall strike the rock, and water shall come out of it, and the people will drink.” And Moses did so, in the sight of the elders of Israel.

Numbers 20:8 ESV

“Take the staff, and assemble the congregation, you and Aaron your brother, and tell the rock before their eyes to yield its water. So you shall bring water out of the rock for them and give drink to the congregation and their cattle.”

Psalm 114:8 (ESV)

who turns the rock into a pool of water,

the flint into a spring of water.

Isaiah 44:3 (ESV)

For I will pour water on the thirsty land,

and streams on the dry ground;

I will pour my Spirit upon your offspring,

and my blessing on your descendants.

Jeremiah 2:13 (ESV)

for my people have committed two evils:

they have forsaken me,

the fountain of living waters,

and hewed out cisterns for themselves,

broken cisterns that can hold no water.

Philippians 4:5–7 ESV

Let your reasonableness be known to everyone. The Lord is at hand; do not be anxious about anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. And the peace of God, which surpasses all understanding, will guard your hearts and your minds in Christ Jesus.
