Psalm 101 Jeremiah wrote that the heart is deceitful! No one can know it but God! [Jer 17:9] It is He that transforms that deceitful heart into something glorious to behold! Jesus reminded the disciples that the angels sing when a person repents before God. “In the same way, I tell you, there is joy in the presence of God’s angels over one sinner who repents.” [Luk 15:10]

In Ps 101, the psalmist gives us three pictures of the heart of men: vs. 2 the perfect heart., vs. 4 A froward (perverse) heart, and vs. 5 a proud heart.

Later, the psalmist would pray: create in me a clean heart, [Ps 51:10]. The author of Proverbs says to guard our heart, [Prov 4:23], and the author of Hebrews challenges those who are drifting to draw near to God with a sincere heart (Heb 10:22] 

Today I need to examine my heart. Is it perfect? (only by the saving grace of God). Next, do I seek to guard my heart against that which is perverse? And lastly, do I seek to have a humble heart?
