Matthew 5: 8 "Blessed are the pure in heart, for they shall see God."
Pure= clean, uncontaminated and undefiled.
Heart= center, thoughts and feelings
Psalm 24:3-5  " Who may ascend into the hill of the Lord? And who may stand in His holy place?
He who has clean hands and a pure heart, who has not lifted up his soul to falsehood, and has not sworn deceitfully.  He shall receive a blessing from the Lord and righteousness from the God of his salvation."
Hebrews 12:14 " Pursue peace with all men and the sanctification without which no one will see the Lord." Sanctification= purity
I John 3:2-3 " Beloved, now we are children of God, and it has not appeared as yet what we shall be. We know that, when He appears, we shall be like Him, because we shall see Him just as He is. And everyone who has this hope fixed on Him purifies himself, just as He is pure."
Revelation 22: 4 " and they shall see His face, and His name shall be on their forehead."
Purity, free from contamination or defilement, is accomplished by cleansing.  Vines tells us that in the NT it speaks of moral and ethical purity. Sincerity.  Unmixed, uncontaminated by sin.  Peter tells us that we purify our souls " in obedience to the truth" ( I Peter 1:22a).
Jesus speaks of purity and cleansing during His time in the upper room, right before His death.  " You are already clean (pure) because of the word which I have spoken to you."

To see God face to face, to be transformed into His likeness at His coming, to come into His Presence - depends on our cleansing from all impurity.  A cleansing of our hearts, of all our thoughts and all are feelings. Purified morally and ethically.   That cleansing comes from hearing the Words of Jesus AND living in obedience to the Truth.
We must hear the Word of God - consistently , daily, sincerely taking heed of it.
And then we must submit to It. Walking in the Truth, abiding in Jesus,  a branch - abiding in the Vine.
Connected in genuine faith,  with His life flowing into us and through us, bearing fruit for the Vinedresser.
Then ... we will see Him face to face.   Fix your hope on this!  Pursue it!

Jesus,  speak Your Word into our hearts and minds today.  Cleanse us with Your Truth and fill us with Your Spirit. Help us to constantly abide in You.  We want to see You.
