The fear of the LORD is the beginning of wisdom: a good understanding have all they that do his commandments: his praise endureth for ever (Psalm 111:10).
In Matthew 22:29, while in dialogue with the Sadducees, Jesus said to them, “...Ye do err, not knowing the scriptures, nor the power of God.” People make mistakes, and go wrong in their choices and actions, because they lack revelation knowledge of what the Spirit of God can do through the power of God’s Word in their lives. The Word of God is the wisdom of God, and to walk outside the Word is to walk in error.
The accurate teaching of the Word of God is so important. Many Christians around the world are taught God’s Word, but not the accurate teaching of it. This explains why some aren’t living victoriously, because for anyone to live a victorious life, he has to understand the Scriptures first. When the Word is taught accurately, it not only imparts faith to you, but also makes you strong and effective in your walk of faith.
Ephesians 4:11-13 tells us something that the Lord did: He gave the five-fold ministry gifts for the benefit of the Church. Look at it: “And he gave some, apostles; and some, prophets; and some, evangelists; and some, pastors and teachers; For the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ: Till we all come in the unity of the faith, and of the knowledge of the Son of God, unto a perfect man, unto the measure of the stature of the fulness of Christ.” How important this is! This is why every Christian must be a member of a church where God’s Word is taught, and accurately too.
Christianity is founded on the Word, and sustained by the Word. Therefore, you can only be victorious by the Word. Study the Word by yourself, and for yourself, and make certain to get accurate teaching of the same, so you can increase in knowledge, and be able to deal excellently in the affairs of life as God will have you do.
