Predestination is not true and it goes against the nature of God.I will point out why they are wrong and it is a misinterpretation of scriptures.
God already had all things planned before He laid down the foundation of the world.
The Bible says that God calls things that have not already happened as though they already happened for if it is a future event God wants to happen it will come to pass without failure.
If it is a future event that God has planned it is the same as it already happened in the beginning,which everything already happened in the beginning for God already had everything planned before He created the world.
The Bible says that the Lamb was slain from the foundation of the world,but we know it did not actually happen until 4000 years later because God calls things that have not already happened as though they already happened.
When the Bible says we are predestined to salvation it does not mean that God picks and chooses who will be saved but God had the plan to give mankind salvation before He laid down the foundation of the world so it is the same as the saints already having salvation in the beginning because God calls things that have not already happened as though they already happened,and that salvation is to mankind in general whoever chooses that salvation.
God picks and chooses without our willingly choosing salvation and to follow Jesus goes against the nature of God that is good.
The Bible says that all have sinned and come short of the glory of God so everybody is in the same boat.
The Bible says that Jesus lights everybody that come in to this world so everybody has a chance to see the light of Jesus if they choose.
The Bible says that God is not willing that any should perish but ALL come to the knowledge of the truth and be saved.
The Bible says that many are called but few are chosen which a person would have to be called while on earth,so God chooses when he knows a person is seeking the truth and knows their heart and then He chooses them but only some people actually make it to heaven for many are called but few are chosen.
According to this scripture above if God picks and chooses then all that He called would be chosen for why God call someone that did not have a chance to be saved,they would all be saved that He called,but it says many are called but few are chosen which could only happen on this earth.
The Bible says that whosoever will can be saved and Jesus told everybody to repent not certain people.
And there is many more scriptures .
God does not pick and choose who will be saved in the beginning but is a misinterpretation of the scripture we are predestinated to salvation which means that God already had the plan to give salvation to mankind before He laid down the foundation of the world so it is the same as if the saints already have salvation in the beginning and that salvation is to mankind in general.
Just like the Lamb was slain from the foundation of the world but it did not actually happen until 4000 years later,the saints have salvation in the beginning but did not actually happen until 4000 years later when the Lamb came and gave that salvation to whoever chooses that salvation.
While we are on the subject of misinterpretation of scriptures I want to point out the controversy between saved by works and not saved by works,and there is not a contradiction.
Not saved by works means we are not saved by any works that we can do to try to get to heaven apart from Jesus Christ or to try to do works to get to heaven apart from the works of the Spirit.
Saved by works means we have to have works to have faith activated in our life which are not works of our self but works of the Spirit which we should do anyway and have to do.
