I agree.
Now; just WHAT does 'persevere' mean?
Some would say "do good works".
I say "continue to trust in the Lord."
Luke 18:13
But the tax collector stood at a distance. He would not even look up to heaven, but beat his breast and said, God, have mercy on me, a sinner.
You are most correct. It definitely means to continue to trust Him.
God bless!
