Topic: Psalm 18:20-26
"Blessed are the pure in heart for they shall see God" (Matthew 5:8, KJV).
Jesus had a flashpoint against the hypocrisy of the Pharisees. They professed to be something they were not. Externally they did everything right, adhering meticulously to all the details of the law, yet He referred to them as being "whitewashed tombs" internally, and being "full of dead men's bones." Thus, obviously, the "pure in heart" did not apply to the Pharisees, according to His view of them.
In John 14:21, Jesus says, "The one who obeys Me is the one who loves Me and because he loves Me My Father will love him and I will too and I will reveal Myself to him." That is another way of saying what He said in the verse in Matthew above. The pure in heart shall see God because He will reveal Himself to those who obey, and only the pure in heart obey.
If God seems impersonal to you, far off and unreachable, you may want to look into the mirror of your heart to see if anything there would grieve or quench the Spirit, short- circuiting His communication with you.
You may be sure of this promise of God: The pure in heart will experience the reality of His presence within.
If for some reason this is not your experience, God has made provision whereby you can have vital fellowship with Him. Breathe spiritually. Exhale by confessing yours sins, and inhale by appropriating the fullness of God's Spirit. Begin to delight yourself in the Lord and in His Word, asking God to give you a pure heart, and you may be assured that God will become a reality to you.
Because I desire to have a close personal relationship with God and to live a supernatural life, I will keep my heart pure before Him.
