My two cents: the people in this passage aren’t tender consciences, they’re presenting a résumé, not pleading for mercy. Assurance starts with coming to Christ empty-handed, and obedience grows from there.
The Father’s will isn’t as mysterious as we make it sound. John 6:40. Look to the Son and believe in him.
The test is whether I’m clinging to Christ, confessing sin, returning when he corrects me.
A genuine Christian cares that Jesus saves unworthy people, not a resume of spiritual accomplishments.
But these folks kept pointing to all their good Christian deeds as their whole defense. Their confidence was in how good they were at worshiping Jesus, not in being known by him.
