The power of the Word

“For the word of God is living and active. Sharper than any double-edged sword, it penetrates even to dividing soul and spirit, joints and marrow; it judges the thoughts and attitudes of the heart.” Hebrews 4:12
We should always quote the Bible when we are witnessing to people. It has great power that even our most eloquent and persuasive words do not. It is living, because it was God-breathed, and when we speak it forth, the Holy Spirit empowers those same words to those who hear it. The Word of God has the power to penetrate to a person’s spirit. This is the deepest part of a person, within their soul. The soul is the place of emotions, personality, and decision-making. This is the furthest that human persuasion and psychology can reach. Only God can reach into a person’s spirit; only God can regenerate them from within.
You will come across some people, who when you say, ‘The Bible says...’ will respond, ‘I don’t believe the Bible.’ It’s tempting at that point to try and convince them some other way. But don’t do it! Keep quoting the Bible. It alone has the power, because the Holy Spirit works through it, to save people.
And the Bible continues to have power in the lives of believers. We can often be blind to the true state of our heart. We may think we are doing something out of right motives, when actually it is self-serving. The Bible will expose these attitudes within us, if we will listen to God speaking to us through it. This is why it’s important for all believers to read the Bible regularly, preferably daily, for the spiritual cleansing that only comes by the Word (Eph. 5:26).
