Joshua was making a public declaration to the Israelites that he and his home would serve, love and proclaim God as King. The connection between that verse and my core point is that there are influences in your life (people, pride, satan) that can convince you to be silent in a moment, when you ought to sing God's praise.

I agree that we do not choose God, we are either made to see or blind, however, free will exists.

If free will exists, then how we choose to proclaim or be silent is our own choice. Do you sing God's praise, do you let your discomfort in a moment silence you? Like Joshua, do you proclaim God as King publicly or not? Even satan knows Christ is God, but satan is not saved. Therefore, knowledge alone is not salvific. Rather, salvation comes from our coming underneath the righteousness of Christ, so that God's holy justice will "pass over" our transgressions, as we are "clothed in His righteousness".

If there were no free-will, then how might satan know Christ's divinity, and yet not be saved by it? He freely chose, in prideful arrogance, to deny God's gift of salvation, grace and mercy. As do some of us.

Make sense? Its so complicated I struggle holding it together myself. I write so that I can explore the depth of these truths and better comprehend God's ways. This is why its so lovely when someone like yourself shares your thoughts or feedback, because it helps me explore the adequacy of my comprehension.
Thanks for the comment.
Have an awesome day. God bless.
