"One son had for a time cut himself off from the household, not discerning the father's love. But now he has returned, and the tide of joy sweeps away every disturbing thought. “This thy brother was dead, and is alive again; and was lost, and is found.” COL 209.1"
"For this my son was dead, and is alive again; he was lost, and is found. And they began to be merry."
EGW directly quotes and elaborates on the verse.
