What is election
Election is God’s choice of those that He would save (Eph 1:4; II Thess 2:13; II Tim 1:9), and He assigned them to Jesus Christ to be saved (John 6:39; 10:29). Jesus declared that He would not lose a single one of God’s elect – He would save every one of them (John 6:39; 17:2). This is called election in the Bible – God’s choice of rebel sinners that He would save (Rom 8:33; 11:7).
Predestination is God’s certain plan and purpose for all the elect to end up in heaven – their final destination. God’s predestination of the elect to heaven is so certain that Paul could write about their glorification in the past tense (Rom 8:28-30). God has adopted each of the elect to be His child and has promised each one an eternal inheritance – both events predestinated (Eph 1:5,11).
