Actually, it means God's foreknowledge of his own decree to give them saving faith.
Read it again. . .God works in us both to will and to do.
Scripture presents no such spiritual freedom, but quite the contrary, Jesus said we are slaves to sin (Jn 8:34). . .slaves are not free.
Free will is a construct of man, not of Scripture. . .based on the assumption that if God holds man responsible, then man must have free will.
Biblically, it is not so. . .man is a slave to sin (Jn 8:34).
God does not decree that some persons will not be saved. God does not need foreknowledge of His own decree. He can remember it. As in Romans 8:29 God foreknows who will say yes to the Gospel when they hear it. And many children would have heard Paul, but not understood, due to young age, but if they died, as without modern medicine many did, they would have entered the light of life. It is automatic for them.
Philippians 2:12,13 NKJV reads
12Therefore, my beloved, as you have always obeyed, not as in my presence only, but now much more in my absence,
work out your own salvation with
fear and trembling;
13for it is God who works in you both to will and to do for
His good pleasure.
We must be responsible to use our salvation and be reverent.
If we attend church, and stand by, and don't choose but just wait for grace, nothing will happen. If we worry, also there is no good result. And there is a kind of sorrow that does not lead to repentance. 2 Corinthians 7:10. We must know not to harden our hearts and choose life, then with the Holy Spirit inside sealing us, we have the option to work out by surrender, dying to self, dying the seed, to manifest the fruit of the Spirit Galatians 5:22.
Also in Romans 8:11, Paul says we can ask and receive the power of the resurrection. A great power in the fight against sin. And by His Spirit we put to death fleshly sin deeds.
Without surrender, God will not force through His grace. You won't manifest love, and great qualities to bear are faith and patience, as you mentioned earlier, great for God's grace and will to come to effect. You still have to decide on praying, and wise words, for with faith and patience comes answers.
We begin to overcome slavery when born again. Receive the Spirit and the power of the resurrection, the power of Jesus' blood, makes the heart clean, walking in love is not slavery.
Even in the OT Isaiah 1:18-20, reasoning with God, could make the heart clean. And Isaiah 10:27, the anointing breaks the yoke of bondage, the Spirit against sin bondage, slavery. Luke 4 has Jesus anointed to set prisoners free, mend broken hearts, heal...
In this life we can be set free, I have gained some of that, and in the next life, the elect have no sin or slavery. No threat, free choice and only perfect choices for the completely mature.
In context John 8:34-36 NKJV.
34Jesus answered them, “Most assuredly, I say to you, whoever commits sin is a slave of sin.
35And a slave does not abide in the house forever,
but a son abides forever.
36Therefore
if the Son makes you free, you shall be free indeed.
You are born again, your new identity and behaviour leads to eternal life as above.
John 3:14-17 NKJV
the Son of Man be lifted up,
15that
whoever believes in Him should
[c]not perish but have eternal life.
16For
God so loved the world that He gave His only begotten Son, that
whoever believes in Him should not perish but have everlasting life.
17For God did not send His Son into the world to condemn the world,
but that the world through Him might be saved.
God wants each and every person, died for all, for whosoever may come. To save all, 1 Timothy 4:10, God the saviour of all especially those who believe, and this should include those non believers in dark corners of Africa... who follow their conscience, and love people as adults, and children who perish. The rejection of grace is something learned, as with Pharaoh is Moses day. Alternately, he could have chosen from boyhood to worship with the Hebrews, but living to mature age he hardened his heart. If he died as a boy, He would have been better off.
