This promise of Jesus represents the future state of the glorified to consist not in locality, but in character; the essence of its bliss is the full vision and fruition of God. Our attention is called away from all vague and indefinite theories about the circumstantial of future happiness. The one grand object of contemplation, the "glory which excels," is the sight of God Himself! The one grand practical lesson enforced on His people is the cultivation of that purity of heart without which none could see, or (even could we suppose it possible to be admitted to see Him) none could enjoy God!
[John MacDuff]

Matthew 5:8 ... Blessed are the pure in heart: for they shall see God. ❤
