Blessed are the pure in heart, for they will see God. - Matthew 5:8
Each of the Beatitudes has two components: the condition called blessed (or “happy”), describing the heart state of citizens of the Kingdom of Heaven; and the resulting condition of life in the Kingdom. As we have seen in our study of the other Beatitudes, either one of these phrases might not mean what we assume on first reading. For one thing, we are sinful by nature and not in tune with God’s way of thinking or viewing the world. For example, the first Beatitude, “Blessed are the poor in spirit,” might refer to someone who has a strong sense of being economically disadvantaged, or it might describe someone with low self-esteem. Rightly understood, though, it refers to someone who is aware of their sin and guilt before God and knows they have no spiritual currency with which to settle their debt. Anyone who feels this way sees the true meaning.
“Blessed are the pure in heart” is another one of the Beatitudes that is frequently misread. Quite often we read it as if it refers to those whose hearts are clean, without spot or stain of sin. Such a person will indeed see God, and all those who believe in Christ are washed clean and made pure by His blood. But if we look elsewhere in Scripture, we see there is another interpretation. Psalm 24:4 says, “The one who has clean hands and a pure heart . . . does not trust in an idol or swear by a false god.” Read this way, someone who is “pure in heart” has a heart entirely devoted to God, a heart that is not mixed or divided or combined with anything else. Food that is “100% pure” does not have any additives or fillers. Hearts that are 100% pure are set on God and nothing else—no private agendas, not secret idols.
