If we think of this as good counsel we’ve lost sight of the gospel. If we could do better, The Father would have not needed to send Jesus.
Let’s resolve not to try harder or do better. Let’s resolve to respond to the gospel and receive his peace that comes from grace. As David said..,
“The salvation of the righteous is from the Lord; he is their stronghold in the time of trouble. The Lord helps them and delivers them; he delivers them from the wicked and saves them, because they take refuge in him.” Psalms 37:39-40 ESV http://bible.com/59/psa.37.39-40.esv
