'I will give them a heart to know Me, for I am the LORD; and they will be My people, and I will be their God, for they will return to Me with their whole heart.
I will give you a new heart and put a new spirit in you; I will remove from you your heart of stone and give you a heart of flesh.
Come, let us sing for joy to the Lord;
let us shout aloud to the Rock of our salvation.
Let us come before him with thanksgiving
and extol him with music and song.
For the Lord is the great God,
the great King above all gods.
In his hand are the depths of the earth,
and the mountain peaks belong to him.
The sea is his, for he made it,
and his hands formed the dry land.
Come, let us bow down in worship,
let us kneel before the Lord our Maker;
for he is our God
and we are the people of his pasture,
the flock under his care.
Today, if only you would hear his voice,
“Do not harden your hearts as you did at Meribah,
as you did that day at Massah in the wilderness,
where your ancestors tested me;
they tried me, though they had seen what I did.
For forty years I was angry with that generation;
I said, ‘They are a people whose hearts go astray,
and they have not known my ways.’
So I declared on oath in my anger,
‘They shall never enter my rest.’”
Hebrews 3: 7-19
Therefore, as the Holy Spirit says,
“Today, if you hear his voice,
do not harden your hearts as in the rebellion,
on the day of testing in the wilderness,
where your fathers put me to the test
and saw my works for forty years.
Therefore I was provoked with that generation,
and said, ‘They always go astray in their heart;
they have not known my ways.’
As I swore in my wrath,
‘They shall not enter my rest.’”
Take care, brothers, lest there be in any of you an evil, unbelieving heart, leading you to fall away from the living God. But exhort one another every day, as long as it is called “today,” that none of you may be hardened by the deceitfulness of sin. For we have come to share in Christ, if indeed we hold our original confidence firm to the end. As it is said, “Today, if you hear his voice, do not harden your hearts as in the rebellion.” For who were those who heard and yet rebelled? Was it not all those who left Egypt led by Moses? And with whom was he provoked for forty years? Was it not with those who sinned, whose bodies fell in the wilderness? And to whom did he swear that they would not enter his rest, but to those who were disobedient? So we see that they were unable to enter because of unbelief.
Therefore, since we have been justified through faith, we have peace with God through our Lord Jesus Christ, through whom we have gained access by faith into this grace in which we now stand. And we boast in the hope of the glory of God. Not only so, but we also glory in our sufferings, because we know that suffering produces perseverance; perseverance, character; and character, hope. And hope does not put us to shame, because God’s love has been poured out into our hearts through the Holy Spirit, who has been given to us.
