The Holy Spirit’s sword is the Bible, so says Paul in Ephesians 6. The Bible is part of the Christian’s armor. It is truth that guides and protects the Believer in his walk with God.
The Holy Spirit and the Bible are distinct from each other. David said, “The Spirit of the LORD spoke by me, And His word was on my tongue.” (2 Sam. 23:2). The Bible is the work of the Holy Spirit. A person who reads the Bible has the Word IN him having, which is not the same as the indwelling Holy Spirit which is given once the body is cleansed or sanctified at Baptism (Acts 2:38; 5:32). We are therefore encouraged to diligently study the Bible and be approved workman who don’t need to be ashamed (1 Tim. 2:15). The Lost need to hear it because “faith comes by hearing, hearing by the Word of Christ” (Rom. 10:17). By studying the Bible, faith is established by and in the Truth and a person gains a clearer understanding of right and wrong (Heb. 5:14). The Hebrew writer said the “word of God is living and active and sharper than any two-edged sword” (Heb. 4:12). The Bible, given by the Holy Spirit, is indispensable to spiritual growth. The Holy Spirit produced the Bible, guiding inspired Apostles and Prophets to pen it, so that we would read it and understand God’s will.
The Holy Spirit does not permit us to bypass the important step of reading the Bible. Some people claim that the Holy Spirit helps them to understand the Bible. This isn’t true. The Holy Spirit did not give a Book that is unintelligible. If someone loves the truth, he will understand the Bible. Only those who close their eyes and ears misunderstand. The Bible is understandable by the Christian and non-Christian. It is not written in a hidden language or format so that the reader needs divine assistance from the Holy Spirit to understand it. The Holy Spirit gave us God’s word to be followed. No one can say they learned God’s truth apart from reading the Bible. It must be read or heard in order to know God’s will.
If a person loves the truth and seeks God, he may understand the Gospel and how to obey it. God’s judgment is against “those who do not know God and to those who do not obey the gospel of our Lord Jesus” (2 Thess. 1:8). The Gospel is believable and obeyable (made up word) otherwise God would be unjust to require it. Jesus said for the disciples to “preach the Gospel to all creation“. If someone doesn’t believe the Gospel, he will be eternally lost. Jesus didn’t say, “Go preach the Gospel to all creation and then the Holy Spirit will follow-up to make it understandable.” Whether it is heard from the mouth of the Apostle or from the pen of the Apostle, the word of God is understandable. This is an important point to caution against the idea that one needs the Holy Spirit Himself to help understand the Scriptures. It’s a false idea that creates a false need, it makes God a respecter of persons, and it is responsible for a lot of error and division.
When you hear the Gospel, you will understand the need to turn from sin and be baptized. Acts 2:38 shows the way to receive the Holy Spirit indwelling, God’s seal upon the Saved. The Ethiopian Eunuch understood his need to be Baptized after he heard about Jesus. Acts 8 says that Jesus was preached to him and it prompted him to say, “what prevents me from being baptized?” To know what to do requires no special intervention from the Holy Spirit to understand what to do.
In the Bible, God has given us “everything pertaining to life and godliness” (2 Pt. 1:3). We need nothing else to understand it but an open heart and mind. So if you would be prepared for spiritual battle, take up the “sword of the Spirit, which is the Word of God.”
