Humility: When one exercises humility a doorway opens to deeper communion with one's true self which is a process of one's heart becoming pure. The sixth Beatitude of Jesus is 8Blessed are the pure in heart, for they will see God. This opens blessing,
"they will see God," opens an immense concept of who God is and who is accessible.
The word “mercies” is from the Hebrew word 'chesed', meaning God's "Loving-kindness" or “God’s enduring love.”
"Less than the least of all God’s mercies.” I found on a devotion site that this was the motto 17th-century English poet and clergyman George Herbert engraved on his signet ring, and it was the phrase with which he signed his letters and books.
Jacob (whose name means 'usurper') spoke these words when he pondered God’s goodness despite his own sin and shame:
“I am not worthy of the least of all the mercies and of all the truth which You have shown Your servant” (Gen. 32:10).
Jacob then relying solely on God’s faithful love, cries out: “Deliver me!..”
Humility and contrition are the keys that open our hearts to the heart of God.
