Question: If there is predestination, then why seek souls?
Answer: This question has to do with realizing that to human understanding there are two irreconcilable truths. They are God’s sovereignty and man’s responsibility. All who will be redeemed by the precious blood of Christ are God’s elect. Every person who lives on earth is responsible to believe the gospel of God as found in the Bible. It is impossible to now reconcile these truths satisfactorily in our thinking. In fact, over many years the countless volumes written in part for this purpose, have all failed. We must let go of our reasoning and simply believe God!
God foreknows everyone who will be redeemed. We do not. But we have the privilege from God to carry the message of the Gospel to everyone, which we should be willing and ready to do. God then saves the elect by the preaching of the Gospel: they come to Christ. Not one of God’s elect will be lost. They believe the Gospel and trust in Christ. Many more people will hear and refuse to believe. They will be lost, they are responsible to believe, but they will not come. Read Romans chapter 10. Perhaps this is enough to answer the last part of the question.Now the first part of the question: Predestination really has nothing to do with seeking souls; has nothing to do with being saved or lost. The four verses of Scripture that tell us about predestination are Romans 8:29, 30 and Ephesians 1:5 and 11. These four verses, briefly, tell us about the blessings God has predetermined believers shall have. These verses have nothing to do with humanity at large. No one is predestinated to be saved or lost. But God has predetermined that believers shall be “conformed to the image of His Son” and have “an inheritance” in Christ “according to the purpose of Him who worketh all things after the counsel of His own will.” To repeat, predestination has to do with the blessings Christ’s redeemed ones will have for time and eternity according to God’s determination—not God choosing them.
