It is clear throughout scripture that man is given "free will" to choose and decide. From the garden of Eden, to Noah's Ark, to Moses parting the Red Sea... we see CHOICES.
However- how can mankind make free choices and yet God know them beforehand? If God already knows and is in full control of the universe... are any choices really free after all?
The most prominent passage of scripture about pre-destination can be found in Ephesians chapter 1.
In Ephesians 1:5 the Greek word translated “predestined” is PROORISAS. It means “designated,” “foreordained,” or literally “BEFORE SEE.”
It is in the Greek aorist tense and refers to an act in the past once and for all. It happened “before the foundation of the world.” What is referred to here happened in a pre-creation conference between the God the Father, God the Son, and God the Holy Spirit.
Before creation, by decree of the Trinity, a boundary was set. It was predetermined that all who came within that boundary would be saved. The boundary is defined as being “in Christ.” Those in Christ shall be saved.
God in His sovereign will DECREED “in Christ.”
Man in his free will DECIDES whether or nor to be “in Christ.” It is an option open to the “whosoever” believes as written in John 3:16.
We all know that Christ died for all men. Jesus said, “No man comes to me, except the Father… draws him” (John 6:44). He further stated, “And I, if I am lifted up from the earth, will draw all peoples to Myself” (John 12:32).
Jesus said, “No man can come to me except the Father draw him.” “Draw” is God’s initiative. “Come” is man’s response.
“As many as received Him, to them He gave the right to become the child of God” (John 1:12).
“The Lord is not slack concerning His promise, as some count slackness, but is longsuffering toward us, not willing that any should perish but that all should come to repentance.” (II Peter 3:9)
“And whoever desires, let him TAKE the water of life freely” (Revelation 22: 17). Keep in mind that take is an action that is a choice...
To summarize, predestination and free will CAN co-exist. Predestination speaks of those who enter into Christ's likeness.... Those who are drawn into Christ must freely choose & take action through their own desire to enter in to the heavenly calling of Christ Jesus.
