As Christians, speaking to others about the Word can be a stretching in many circumstances.
This can be far from our comfort-zone, especially when someone is coming strong with unlearned opinions and doctrines from the Bible contrary to the revelation of God. Most Christian theology we hear today from peers and churches were developed only hundreds of years ago. Church denominations may not sound like a negative thing, but when teaching is not regenerating and restoring the souls it becomes a matter of life and death. In these moments of evangelism and fellowship, God calls us to defend the gospel.
Philippians 1:16-17: “The former preach Christ from selfish ambition, not sincerely, supposing to add affliction to my chains; but the latter out of love, knowing that I am appointed for the defense of the gospel.”
Defense in Greek is apologia.  This is where we get the word apologetics. In our Western culture of Christianity, apologists such as: C.S. Lewis, William Lang Craig, Ravi Zacharias, and Frank Turek, define apologetics as, “to speak in defense,” or “to give an answer.”
These men speak on various topics and questions like, the existence of God, the historicity of Jesus, moral values, etc. and use a form of apologetics to answer. This style of apologetics uses scientific and philosophical arguments to answer fellow Christians and objections from atheists. This way of theological debates in apologetics is a good tool to use to answer people’s questions. But God shows us there are deeper levels to apologetics than we’ve realized, through His Word.
Apologetics is two Greek words: apo means, “to separate,”  and logos means, “living voice, a speaking, speech, utterance,”  and “divine expression.”  Logos in the Bible is the Word; which Jesus likens to a seed. “The seed is the Word (logos) of God,” (Luke 8:11). This concludes that apologetics, from the Bible means, “to separate the Word or logos of God, through speech and divine expression”.

If the Word is like a seed, this means it has an outer shell and breaks open like a seed. When this happens, it reveals and produces something from inside, like a seed. This is called the rhema of the Word. For example, when Jesus spoke to Satan, He broke open the scripture and said, “Man shall not live by bread alone, but by every word that proceeds from the mouth of God,” (Matthew 4:4). Word in this verse is the Greek word, rhema. This means, “having definite meaning,” of what is being said.  Jesus had separated the logos (shell) of the Word, and revealed the rhema (the definite meaning) of the Word.
By giving the rhema, the revealed Word of God, darkness and ignorance flees because the words of life are given to the person’s soul. When God first speaks to us and leads us to speak to others, it begins at the logos. Through the Holy Spirit, the logos flourishes to the rhema. When placed on a soft heart, it produces fruit, “some a hundredfold, some sixty, some thirty,” (Matthew 13:23). In this season, God is revealing a greater depth of apologetics, not from head knowledge, but by “demonstration of the Spirit and power,” (1 Cor. 2:4). Apologetics in its fullness is from the inscription of God’s living Word written in our hearts, to be seen and read by all who seek the unveiling of Jesus.

“But even to this day, when Moses is read, a veil lies on their heart. Nevertheless, when one turns to the Lord, the veil is taken away. Now the Lord is the Spirit; and where the Spirit of the Lord is, there is liberty.” – 2 Corinthians 3:15-17
