Keith M - You wrote - Free choice - it's in the Bible!
How much of the Bible was addressed to the whole world and how much of the Bible was addressed to God's People?
More to God's People than the Whole World......Look it up.
Can God's People Sin? Of course - Being the people of God does not preclude making choices to sin or not sin. Your example is an admonition to God's People. This example will be followed in thousands of churches today as God's man admonishes the people to obey God. Why? Because God's People can choose to sin or not sin.
But becoming God's People does preclude making choices. Did Israel freely choose God? No, God chose Israel. Our of all the nations of the earth God chose one for his own - Israel, the Elect Nation of God.
If God chose Israel before they knew Him.
And God chose John the Baptist, before He was born.
And God chose Mary, to be the Mother of Jesus.
And God chose Paul, to be the Apostle to the Gentiles.
Why would it ever bother you that God chose you before you were born?
Man, you're in great company!
Have a Great Sunday!
