8 “Blessed are the pure in heart, for they shall see God.
Pureness of heart is clear only to the eyes of God. He knows your heart and its contents. The purification that occurs from within when Christ is invited to dwell there shows through in the life of believers. The contents of our heart guide our words, thoughts and actions. The source of all possible good within us comes from the indwelling of the Holy Spirit in our heart. A pure heart describes the previous beatitudes in summary. Being pure in heart comes from living in God’s light and reflecting it through the qualities Jesus desires for His followers. Pureness is a process achieved through sanctification. It’s the walk each believer has which God uniquely purifies them through trials designed to draw them closer to Him. Some fall away while faith creates holiness. That holiness is what will allow us to have fellowship with God in Heaven.
(1 Peter 1:22-23) 22 Having purified your souls by your obedience to the truth for a sincere brotherly love, love one another earnestly from a pure heart, 23 since you have been born again, not of perishable seed but of imperishable, through the living and abiding word of God
(Hebrews 12:14) 14 Strive for peace with everyone, and for the holiness without which no one will see the Lord.
