You must first be aware God exists. Awareness is the reason for missions, Christian outreach in communities, fans holding John 3:16 signs behind the backstop at baseball games, street preachers in New York City, fish-shaped bumper stickers. God uses all these means to reveal himself.
It’s impossible to achieve the second milestone, acceptance, if you’ve never become aware of God’s existence. You then have a choice, either accept or reject God.
