Psalms 13 and 14, from the Psalmist again, reflect so much of the journey of humanity and intimate relationship with God, as God intended or desires. The Psalms can express ourselves when we lack the words. The Psalms can teach, encourage, convict, remind, exhort and lead in worship and prayer...
In Psalms 13, we hear a heart :
~crying to God
~begging God for mercy
In Psalms 14, we hear:
~faith in God's knowing...and God's justice
~a yearning for salvation through faith
These Psalms are short, so I will copy and paste from my favorite site: biblegateway.com, where you may go and read these very verses in any of a hundred different versions or languages! I copy in King James Version because that version is public domain and I may do so legally:
