Ephesians 1:4 "According as He hath chosen us in Him before the foundation of the world, that we should be holy and without blame before Him in love:"
What does it mean to be "chosen"?
It means that there are certain people that God chosen in the first earth age, to do a task for Him in this flesh earth age. This is not reincarnation, for it is appointed for each of us to go through this earth age, the flesh earth age, once and only once. We read; "...It is appointed unto men once to die [in the flesh], but after this the judgment." Hebrews 9:27 This appointing and choosing took place before the foundation of this earth age; the second earth age [cosmos] that we now live in.
"Without blame" refers to the fact that God intercedes in certain peoples lives. Certain people have free will, while certain others are of God's election, however, God doesn't play favorites. Christ died for the sins of all who will repent; the chosen, and the free-will. All must repent for sins they commit, and love the Lord Jesus Christ, to have the hope of His glory.
"Before the foundation of the world", [cosmos in the Greek, meaning world or earth age.] The "foundation" in the Greek text, is the verb for, "the overthrow". This refers to something that happened in that first earth age, before the overthrow of Satan and his angels that followed him. When Satan fell [war against God], one third of all angelic beings [God's children] followed Satan. Then during that war, there were some who fought against Satan, and those who did, God calls "His Chosen". They took a stand, and were overcomers in that first earth age.
Have you ever wondered why you do the things that you do, at times. It's just like you have a destiny. You have always felt their is more to life, and this world, then what you have been taught. Paul addresses this in Romans 8:27. In verse twenty six it says that there are times in your life when the Holy Spirit makes intercession for you because you don't even know what to pray for.
"And he that searcheth the heart knoweth what is the mind of the Spirit, because he maketh intercession for the saints according to the will of God." Romans 8:27 These saints are "the set-aside ones", or "the chosen". God has a overall plan, and a purpose in that plan just for you. That purpose is to bring back His children to Him; after that overthrow, and in this earth age.
Why would God intercede in a person's life, without them even asking? When your free-will goes against God's purpose for your life, God will intercede. When Paul's "free will" was to destroy all Christians, God's will was to take this highly educated man, and use Paul as the instrument for Him. Paul used to same drive to destroy Christians, that he used later to convert people, after his conversion.
We read that the Lord said; "...For He is a chosen vessel unto me, to bear my name before the Gentiles, and Kings, and children of Israel:" Acts 9:15
Ephesians 1:5 "Having predestinated us unto the adoption of children by Jesus Christ to Himself, according to the good pleasure of His will,"
"Predestined" means "from a prior time", or "required to do a certain thing" in the Greek text. You have a choice of loving God, or loving Satan. God will not interfere with your free will choice to chose Him or Satan. However, that person that proved himself during the overthrow of Satan, were "justified", or earned the right to be called "saints", from that first earth age.
Each soul comes from God, and enters an embryo at conception. This is why Jeremiah was a chosen one. "Before I formed thee in the belly I know thee; and before thou comest forth out of the womb I sanctified thee, and I ordained thee a prophet of nations." Jeremiah 1:5
"Sanctified" thee, is to "set aside, or apart for a purpose". Sins still have to be repented, and the price to pay for them still had to be made. To the predestined, and fore chosen, God can make life so miserable to those out of His will that they will repent. God has a perfect will, and God is always fair.
"And we know that all things work together for good, to them that love God, to them who are the called according to His purpose." Romans 8:28 This verse is directed to a certain people, with a condition attached. This applies to "them who are called according to His purpose." "His purpose" is called God's plan, and God's overall plan is the offering of Salvation to all. That plan includes the teaching of God's Word; to plant seeds to convict; to live our life for Him; and to go and speak where God leads you. God will use you as it pleases Him.
"For whom He did foreknow, He also did predestinate to be conformed to the image of His Son, that He might be the firstborn among many brethren." Romans 8:29 God knew you, and what you were in that first earth age; and then [in that first earth age] God prearranged our destiny for this age. That destiny is to make us conform, or be like His Son, Jesus Christ. Though Jesus is the first fruits to overcome death, there are many that have that victory over death, through Christ's death and resurrection.
"Moreover whom He did predestinate, them He also called: and whom He called: He also justified: and whom He justified, them He also glorified." Romans 8:30 "Justified" means "judged" in the Greek text; God judged them there in that first earth age, and that is why God can and does intercede in the chosen's ones lives. The justified are the priests of the Zadok in the millennium age of Ezekiel 40, for the word Zadok comes from the Hebrew word meaning "the just".
Certain of God's children stood against Satan in the first earth age, and those that did stand, and did not follow Satan; God judged [justified], and He "chose" them then to be used in His eternal plan. Through God's perfect plan, God "predestined", and "ordained" each of them to His purpose to be used in this flesh age. Each of these will also be used in the Millennium age as priests, or called the "Zadok".
When you become a Christian, and God has given you a working over, He is trying to wake you up. God is calling out a people, His people, the "Elect-chosen, and predestined" to stand against the Antichrist [Satan] in this final generation.
