The Bible is perfect because, it is not only the only book in the world that reveals the truth that has the power to make wise the simple, it is the living Word of God. It instructs man in every area of his life. The only way that man can understand his ways is by turning to the Word of God. Man will know that the Word of God is True. All of the Bible's precepts have the power to restore man mentally, physically, and spiritually because the Word of God is alive and active.
The Word is Alive and Active
"For the word of God is quick, and powerful, and sharper than any two edged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart (Hebrews 4:12)
The Law of the Lord is Perfect
"The Law of the Lord is perfect, converting the soul: The testimony of the Lord is sure, making wise the simple. The statutes of the Lord are right, rejoicing the heart: The Commandment of the Lord is pure, enlightening the eyes. The fear of the Lord is clean, enduring forever: the judgments of the Lord are true and righteous altogether. More to be desired are they than gold, yes, than much fine gold: sweeter also than honey and the honeycomb. Moreover by them is Your servant warned: and in keeping of them is great reward. Who can understand his errors? Cleanse You me from secret faults. keep back Your servant also from presumptuous sins; let them not have dominion over me: then shall I be upright, and I shall be innocent from the great transgression (Psalm 19:7-13).
Trust God. Take your burdens to the Lord and leave them there.
