“Blessed are the pure in heart for they shall see God.” (Matthew 5:8)
The people referred to in the Beatitudes are blessed because they belong to the kingdom and they possess the traits that identify them as belonging to the kingdom.
WHAT DOES IT MEAN TO BE “PURE IN HEART”?
A) “Clean on the inside”, not like white-washed tombs which are clean only on the outside.
B) “Sincere” or unadulterated like unmixed wine.
C) “Single-minded” like a faithful husband who has eyes only for his wife.
WHAT DOES IT MEAN TO SEE GOD?
They are blessed because they will see God. In other words, they are those who will be saved because by the purity of their hearts they prove that they really have put their faith in Christ (1 John 3:1-3). Without holiness, no one will see God. The holy God is too pure for sinful hearts to see. To the pure all things are pure; to the impure, all things are impure.
HOW CAN WE BECOME PURE?
The heart is deceitful above all things and desperately wicked (Jer. 17:9). But we can become pure –
(a) By God’s grace. “Create in me a clean heart, O God, and renew a right spirit within me.” (Ps. 51:10) See also Ezekiel 36:25-27.
(b) By confessing our sins: 1 John 1:9
(c) By keeping God’s Word: Psalm 119:9, 11
