Blessed are The Pure in Heart (Matthew 5:8)
Jesus says, “Blessed are the pure in heart, for they shall see God.” The pure heart is sincere, without impure thoughts. The heart is known by God and reveals more about character than external appearance or actions. (1 Samuel 16:7) “…for God sees not as man sees, for man looks at the outward appearance, but the LORD looks at the heart."
Jesus desires that His followers come to Him with a heart in many ways like that of a child. (Luke 18:16-17) "Let the children come to me, and do not hinder them, for to such belongs the kingdom of God. Truly, I say to you, whoever does not receive the kingdom of God like a child shall not enter it." The heart of a child is innocent, sincere and trusting, it easily forgives.
Paul says simply: (Colossians 3:2) “Set your mind on things above, not on things on the earth.” So much in the world brings down while the teachings of Jesus raise you up. (Isaiah 55:8-9) "For My thoughts are not your thoughts, Nor are your ways My ways," says the LORD. "For as the heavens are higher than the earth, So are My ways higher than your ways, And My thoughts than your thoughts.”
Jesus says the pure in heart shall see God. The sixth key to happiness: turn to God’s Word with an open and sincere heart, let His Word reveal those higher ways and thoughts that Isaiah spoke of and allow God to be seen, at least as much as He can be understood in this life.
But ultimately Jesus is referring to the promise of eternity for God’s children: (1 John 3:1-3) “Behold what manner of love the Father has bestowed on us, that we should be called children of God! Therefore the world does not know us, because it did not know Him. Beloved, now we are children of God; and it has not yet been revealed what we shall be, but we know that when He is revealed, we shall be like Him, for we shall see Him as He is. And everyone who has this hope in Him purifies himself, just as He is pure.”
