“I love You O LORD my strength…”  Psalm 18:1
 
“O God you are my God, earnestly I seek You…”  Psalm 63:1
 
“Whom have I in heaven but You?
And earth has nothing I desire besides You.”  Psalm 73:25
 
Putting these three verses of Scripture together, I see a heart that is after the Lord; people with such a heart, I believe, are those whom Jesus describes in Luke  6:21,
“Blessed are you who hunger now, for you will be satisfied.”
And again in Matthew 5:6, Jesus says,
“Blessed are those who hunger and thirst for righteousness, for they shall be satisfied.” 
 
Scripture has much to say about the heart.  What of the heart that is seeking?
It is one that is steadfast and in its steadfastness, this heart sings,
“My heart is steadfast, O God, my heart is steadfast; I will sing and give praise.”  Psalm 57:7
 
“My heart is steadfast, O God;
I will sing and make music with all my soul.”  Psalm 108:1
 
Not only does this heart sing praises, but it does so with a whole heart, joined with the assembly of 
Believers as in Psalms 111:1,
“…I will praise the LORD with my whole heart,
In the assembly of the upright and in the congregation.”  
 
Not only in song in the congregation of one heart, but we see the great example of oneness in the early church in Acts 4:32,
“Now the multitude of those who believe were of one heart and one soul, neither did anyone say that any of the things he possessed was his own, but they had all things in common.”
 
Of the one whose heart fears (reverences) and trusts the Lord, Psalm 112:6-8 says,
“Surely he will never be shaken;
The righteous will be in everlasting remembrance.
He will not be afraid of evil tidings; 
His heart is steadfast, trusting in the LORD.
His heart is established…”
 
We need therefore to guard our hearts;
“Keep your heart with all diligence,
  For out of it spring the issues of life.”  Proverbs 4:23
                                                                                                                                                                                                                                                                                                                        
Our heart expresses our character:     
“For as he thinks in his heart, so is he…”  Proverbs  23:7                                                                                                                                                                                             
     
Our heart is where our faith resides as we see in Romans 10:10,
“For with the heart man believes, resulting in righteousness, and with the mouth he confesses, resulting in salvation.”
 
Jesus does give a warning of evil in the heart as he explains to the disciples the parable he told the multitude 
(Please read Vs. 1-20 for the whole of what Jesus is saying here),
“But those things which proceed out of the mouth come from the heart, and they defile a man.”  Matthew 15:18  
 
Let us seek to have hearts that hunger and thirst after a deeper personal relation with our loving Lord Jesus Christ, He is our treasure.
“For where our treasure is, there your heart will be also.”  Matthew 6:21
 
Thank you Almighty Lord for hearts that respond to Your loving heart!  Amen
