Do I seek to imitate Your holiness, Lord? Help me by Your Spirit to overcome the pressures of the world and the fiery darts of Satan, that I might keep myself unspotted from the world as You have commanded me.It is painstakingly truthful and free from deceitfulness.
A pure heart is a heart that has nothing to do with falsehood. You can see what David means by a pure heart in the phrases that follow it. It is no wonder that David wanted a clean heart, and a right spirit. He who has clean hands and a pure heart, who does not lift up his soul to what is false, and does not swear deceitfully. If purity is the Robe of Heaven, the righteousness of Christ, then I want to diligently strive for purity.
“Blessed are the pure in heart: for they shall see God,” (Matthew 5:8)
