The answer is profoundly simple.
"Your Word is a lamp to my feet and a light to my path" (Psa 119:105).
What ever trials, temptations, stress, anxieties and problems that we may go through, Bible has the solution for overcoming that problem.
Bible has solutions for all the confusions.
For instance, on the Day of Pentecost, there was an unusual happening in the Jewish history. The onlookers of the Upper Room event were quite confused. Concerning the strange things they witnessed, they started asking questions like "How is it?...Whatever could this mean?" (Acts 2:8,12). Apostle Peter was able to instantly defend the new experience of the disciples with the words, "This is what was spoken by the prophet Joel" (v16). The written Scripture was the final authority that gave full endorsement to what was "seen and heard" that day. Not only in this incident, but throughout their life and ministry the apostles referred to "what is written" and checked their preaching and practices against it (2 Cor 4:13; 1 Cor 1:31; Rom 12:19; 14:10,11; 15:2,3).
See what the apostles desired of the believers to learn from them: "You may learn in us not to think beyond what is written" (1 Cor 4:6). Where did the apostles learn this all important principle? Obviously from Christ their Lord who operated well within the limits of "It is written," eventhough His Father had given Him the Spirit without measure! It is ridiculous for anyone to think today that he has an anointing of the Spirit which can go beyond the writing of the Scriptures.
Beloved, beware of extra-Biblical revelations and experiences! Some preachers quote John 20:30 to justify their so-called power manifestations. They try to shelter under the words — "Jesus did many other signs which are not written in this book." But these defenders of novelties fail to look at what John says in the very next verse: "But these are written that you may believe that Jesus is the Christ, the Son of God, and that believing you may have life in His Name" (v 31). In other words, nothing more than what is written is necessary for our life in Christ. Whatever is written is enough! One of the very important rules of Biblical interpretation is, "Do not argue from silence!" Stop where the Bible stops. "Do not remove the ancient landmark" (Prov 22:28).
The carnal man is always interested in novelties. But Jesus is the same "yesterday, today and forever." Therefore "do not be carried about with various and strange doctrines" (Heb 13:8,9).
