God's Choice And Personal Choice
For we are God’s [own] handiwork (His workmanship), [a]recreated in Christ Jesus, [born anew] that we may do those good works which God predestined (planned beforehand) for us [taking paths which He prepared ahead of time], that we should walk in them [living the good life which He prearranged and made ready for us to live].
Sometimes people ask if there's such a thing as predestination. "Can I really say that God prearranged my life?" they wonder. Absolutely! The Bible says He did; we just read it! Also Romans 8:29 says, For whom he did foreknow, he also did predestinate..."
The question then arises: Is God, therefore responsible for everything that happens in my life? Not really, because you a free moral agent; you're responsible for your decisions and actions. Once you become an adult, you have a responsibility for your life, and the onus is on you to make the right decisions in line with God's destiny and perfect will for you.
Just because God predestined your life for something doesn't mean you'll fulfil it. People don't necessarily become what God planned for them to be. It's a personal choice you make to fulfil God's plan for your life and be all that He's destined you to be.
Paul, in his letter to the Colossian church, sent a specific instruction to Archippus, telling him: "take heed to the ministry which thou has received in the Lord that thou fulfil it" (Colossians 4:17). If the man didn't have the responsibility of fulfilling the ministry that God committed to him, Paul wouldn't have instructed him to see to it that he fulfilled it. This also meant it was possible for him not to fulfil it.
Make up your mind you'll be everything God has destined you to be, you'll have do all he predestined you to do, and you'll walk in His preordained pathways.
