Any of us who have been involved in the apologetic endeavor are probably familiar with the comments by hyper-Post Modernist Christians who say “I don’t need any evidence or reasons for what I believe.” In other words, this individual thinks it is more spiritual to trust God because He can only be pleased by faith (Heb. 11:6). Thus, for these people, the object of faith is sometimes described as resting in God Himself (Gen 15:6; Rom 4:24). Even in the New Testament, Jesus confirms this issue (Mark 11:22). And even as God is the object of faith, the author of the Gospel of John directs his audience to Jesus as being the object of faith as well (John 20:31).
Granted, these types of individuals may be ignorant to the fact that the apostles approach to spreading the message of the Gospel is characterized by such terms as “apologeomai/apologia” which means “to give reasons, make a legal defense” (Acts 26:2; 2 Tim. 4:16; 1 Pet 3:15); “dialegomai” which means “to reason, speak boldly” (Acts 17:2; 17; 18:4; 19:8), “peíthō” which means to persuade, argue persuasively” (Acts 18:4; 19:8), and “bebaioō ” which means “to confirm, establish,” (Phil 1:7; Heb. 2:3). 
The reality is that it is impossible to even profess the name of Christ or claim to be of His followers without relying on some evidence. Granted, it is true when someone comes to faith in the Lord, they are not required to give a dozen arguments for why they have decided to made the choice to follow the Lord. However, as time goes on, they will find out very quickly that many will ask them ‘why’ they have chosen to make this decision.
Naturally, many Christians will say they have supernatural certainty for their faith and will commonly say “I experience the Holy Spirit in my life.” Obviously, they can be oblivious to the fact that they sound no different than a Mormon.
What Christians need to remember is that every experience a Christian has is based on what is already found in the Bible. And the Bible is a form of evidence. Thus, Christians are already relying on a form of testimonial evidence and they are also relying on the memories of those that wrote and recorded the events in the Bible. They think the writers of the Bible are telling the truth. The Gospel of John uses words that are usually translated as witness, testimony, to bear witness, or to testify. The total usage of these words in John’s Gospel is larger than any of the Synoptic Gospels. The book of Acts is the next book with the most references to the terms related to eyewitness testimony. We see in the following New Testament passages where testimony and witness is used as a means to verify events:
• Luke 1:4: “Since many have undertaken to compile a narrative of the events that have been fulfilled among us, just as those who were eyewitnesses from the beginning and ministers of the word have handed them down to us, I too have decided, after investigating everything accurately anew, to write it down in an orderly sequence for you, most excellent Theophilus, so that you may realize the certainty of the teachings you have received”
•Acts 2:32: “This Jesus God raised up, and we are all witnesses of it”
• Acts 3:14-15:But you disowned the Holy and Righteous One and asked for a murderer to be granted to you, but put to death the Prince of life, the one whom God raised from the dead, a fact to which we are witnesses.”
• Acts 5:30-32: “The God of our fathers raised up Jesus, whom you had put to death by hanging Him on a cross. “He is the one whom God exalted to His right hand as a Prince and a Savior, to grant repentance to Israel, and forgiveness of sins. “And we are witnesses of these things; and so is the Holy Spirit, whom God has given to those who obey Him.”
•1 John 1:1: “What was from the beginning, what we have heard, what we have seen with our eyes, what we looked upon and touched with our hands concerns the Word of life”
•Acts 10:39 : “We are witnesses of all that he did both in the country of the Jews and (in) Jerusalem. They put him to death by hanging him on a tree.”
•Acts 4:19-20: “Peter and John, however, said to them in reply, “Whether it is right in the sight of God for us to obey you rather than God, you be the judges. It is impossible for us not to speak about what we have seen and heard.”
•1 Peter 5:1: “So I exhort the presbyters among you, as a fellow presbyter and witness to the sufferings of Christ and one who has a share in the glory to be revealed.
•2 Peter 1:19: ” We did not follow cleverly devised myths when we made known to you the power and coming of our Lord Jesus Christ, but we had been eyewitnesses of his majesty.”
•John 21:24: “This is the disciple who is bearing witness about these things, and who has written these things, and we know that his testimony is true.”
•1 Corinthians 15: 3-8: “For I delivered to you as of first importance what I also received: that Christ died for our sins in accordance with the Scriptures, that he was buried, that he was raised on the third day in accordance with the Scriptures, and that he appeared to Cephas, then to the twelve. Then he appeared to more than five hundred brothers at one time, most of whom are still alive, though some have fallen asleep. Then he appeared to James, then to all the apostles. Last of all, as to one untimely born, he appeared also to me. For I am the least of the apostles, unworthy to be called an apostle, because I persecuted the church of God.”
Christians also rely on their perception to know there is a Creator.
“For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who suppress the truth in unrighteousness, because that which is known of God is revealed in them, for God revealed it to them. For the invisible things of him since the creation of the world are clearly seen, being perceived through the things that are made, even his everlasting power and divinity; that they may be without excuse. Because, knowing God, they didn’t glorify him as God, neither gave thanks, but became vain in their reasoning, and their senseless heart was darkened.” (Rom.1:18-21)
In this passage, God’s knowledge is described as “eternal power and divine nature.” Paul lays out the basic principle of cause and effect. Paul says since God is the Designer (God is the cause), His “everlasting power and divinity” are obvious, “through the things that are made” (this is the effect).For Christians, they perceive truth about God, because the basic truths about God are “clearly seen” (Rom. 1:20). Thus, they rely on their perception.
What’s the point?
Christians that claim to be demonstrating a ‘higher’ form of spirituality and trust in God because they say they don’t need any evidence or reasons for their beliefs are ignorant. Keep in mind that I am well aware of the limitations of apologetics and the use of reasons and evidence. But let’s admit we are already relying on some evidence for our beliefs!
