"Blessed are the pure in heart, for they shall see God." [Matthew: 5: 8].  

"Clean Heart" refers to the purity of our heart.  Scripture says that without holiness no one can see God.  If there are unholy thoughts and actions in our lives, our relationship with God will be affected.  The man who has no relationship with God looses the thought of his desire to see God. 

When King David sinned, he requests God to & ldquo; Create in me a pure heart, O God, and renew a steadfast spirit within me.& rdquo;  [Psalm 51:10].  

 No matter how clean we think to protect the heart, it can easily get dirty. It is God who cleanses our hearts using our faith. So we should seek God's help every day in order to create a pure heart in us. Did not God choose us to be His holy people? We should be grateful for it and should sustain holiness.  Scripture says, "Let him who is holy continue to be holy."  [Revelation 22:11] .  We, His holy people, should sing praises to Him and celebrate the remembrance of His holiness and see God daily.  Amen.
