The concept is this: man, in his natural state before salvation, is corrupted in all areas of his life due to the Fall. He is spiritually dead, in fact, and requires a spiritual resurrection in order to enter into a relationship with God. Therefore, in his natural state, he is totally helpless to do anything for himself in the real of spiritual life. He cannot cause himself to come to life again. Therefore, God must spiritually resurrect him to new life. This resurrection is called being "born again", or being "born from above".
It would have to be for if we had the power to be right with God then Jesus would not have to come to be the Savior.
But the Bible says there is no good thing that dwells in the flesh, and the Spirit and flesh are contrary to each other.
And what saves us is being perfected in love which we cannot do being in the flesh, but by the Spirit we can perfect ourselves in love.
Which out of faith, hope, and charity, love in action, charity is the greatest, and faith works by love, and out of all we did on earth only love will go on forever and faith, and hope is not needed in heaven.
Also the Bible says that no person comes to the Son unless the Father draws them.
And no person says Jesus is the Lord, but by the Holy Ghost.
So it takes the intervention of God to cause a person to accept the truth for the flesh will reject it on its own.
And for anybody that says that God chooses in the beginning who will be saved, and not saved without their choice then God's kingdom is not true love, and He is not evil to condemn people that have no choice but to reject truth.
And many are called but few are chosen so God does the calling and choosing on earth, which not many noble, not many wise after the flesh, not many mighty are called because their heart condition is not right to be called.
Which God says that He wants all people to be saved, and Jesus lights every person that is born in this world so everybody has the chance to see the light of Jesus, and the Spirit and bride say Come, and anybody can have that salvation.
So that is enough to show God gave us a choice, and love is the greatest asset a person can have, and God is love, and only love will go on forever, so why would God want robotic love where they do not have a choice but to say I love you seeing no other alternative.
And God said that He is no respecter of persons, and what makes you to differ from another, and all have sinned and come short of the glory of God, and if you offend in the least of the law you offend in all so what criteria would God be using to choose people if we do not have a choice.
God calls things that have not happened yet, as though they already happened for if it is a plan of God to happen in the future it is the same as if it happened in the beginning for it will surely come to pass with no hindrance.
Like the Lamb was slain from the foundation of the world, and the prophets blood shed from the foundation of the world, and all the works were finished from the foundation of the world although they were future events.
So the saints predestined to salvation means that God already had the plan to give people salvation before He laid down the foundation of the world so it is the same as if they already have that salvation in the beginning, and this salvation is to whoever wants it for God's kingdom is love, and He is not evil but allows anybody to be saved.
Which Peter said that God is no respecter of persons but all people in every nation if they do righteousness they are accepted with Him.
2Ti 3:4 lovers of pleasures more than lovers of God;
2Ti 3:5 Having a form of godliness, but denying the power thereof: from such turn away.
2Ti 3:6 For of this sort are they which creep into houses, and lead captive silly women laden with sins, led away with divers lusts,
2Ti 3:7 Ever learning, and never able to come to the knowledge of the truth.
I believe they want to believe that God chooses without their choice so they can believe they cannot fall so they can enjoy sin and believe they are still right with God, which they do not want to let go of the flesh and that is why they are ever learning and never able to come to the knowledge of the truth.
