One can find multiple biblical mandates supporting apologetics in the Bible. In Philippians, (1:7) Paul states that he is appointed for the defense and conformation of the Gospel. 1 Peter 3:15-16 states that we (the church) should always be prepared to give an answer to everyone who asks about Christ. In these two versus we find the necessity of apologetics within our culture. Many believe that apologetics is unnecessary to practice however, based off these biblical texts, it seems that neither Paul nor Peter agreed with this statement. Those who maintain a biblical worldview and believe that the Bible is “God breathed” must recognize the importance of apologetics. The Lord is clear that He will use His prophets to communicate His ultimate will and direction. If you believe this, then it is hard to refute the validity and importance of apologetics. The Bible is clear that we are to defend, confirm, and give answers regarding our faith.
There are many types of apologetic arguments found in the Bible. The Bible itself is its own apologetic. Among others, the Bible uses things like: The Miracles of Jesus and His Disciples, Fulfilled Prophecies, Jesus’ unique authority, arguments from Pagan sources, and even suffering to defend and support Christianity.
Miracles and Acts of Power:
There are many examples of miracles in the Bible, performed through different people. God performs miracles in the Old Testament (Moses and the parting of the Red Sea, [Exodus: 14] Elijah and the prophets of Baal [1 Kings: 18]) Jesus performs miracles in the New Testament (Raised the dead [John:11], water to wine [John:2] , etc.) Jesus’s disciples also performed miracles after the resurrection (Peter: 3, Acts:20, 1 Corinthians: 12, etc.) The miracles performed in both the New and Old testament serve as powerful apologetics to those who witnessed them and even to those who didn’t. They proved the power and authority of God while simultaneously disproving the power and authority of other idols/deities found within the culture of that time.
Fulfilled prophecy is an apologetic that is often found within the New Testament. The main point with this apologetic is that Jesus fulfilled all Old Testament prophecies. Old Testament prophets such as Isiah, Daniel, and David predicted a multitude of things regarding Israel and the Messiah -all of which were ultimately fulfilled by Christ. This was, and is, an important apologetic when regarding Jews that had yet to convert from the Law of Moses to Christianity.
Arguments From Pagan Sources:
In the book of Acts (Chapter 17) Paul gives a speech to Athenian philosophers and quotes pagan poet Aratus to support that we are God’s offspring and that they’re perception of God is therefore misconstrued. Paul contextualizes the poets quote in support of Christianity and therefore could turn their own poets’ words against their already established pagan beliefs. This serves as a great form of apologetics to those who believe in different doctrines or have a pre-existing faith other than Christianity. Finding common teachings within another’s faith (other than Christianity) and contextualizing them in support of the Bible is a great apologetic to practice as it starts with common ground.
Jesus’ Unique Authority:
Unlike teachers before Him, Jesus spoke from an authoritative perspective. Instead of teaching from tradition or previous views of the law, Jesus set Himself apart by the way He carried out His teachings. They were unlike any other. To this day the authority of Jesus attracts the unfaithful.
Suffering and sin can be used as strong arguments to the existence of God. Basically, humanities desire for good (or not to suffer) is derived and founded in the fact that we are created in the image of God. We are instilled with the knowledge of right and wrong and instinctively desire rightness and goodness because that is what our creator desires.
