The anointing helps you to understand  all things

But the anointing which ye have received of him abideth in you, and ye need not that any man teach you: but as the same anointing teacheth you of all things, and is truth, and is no lie, and even as it hath taught you, ye shall abide in him. 1 John 2:27 

The Bible and all scriptural teachings are well understood by the unction of the Holy Spirit, the anointing. The reason why you will need to understand the scripture by the anointing is that the scripture is written by the inspiration of God. 2 Timothy 3:16 All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: If you should read the Bible like other books you will not get the message of God right well.

Of most important of the anointing is that it guides you to know the true teachings of the gospel. if any false prophet or teacher disguise Himself a minister of God, by the anointing you can easily discriminate from His teachings if He is of God.

Dear reader, are you yet to receive the anointing? first of all thirst for the Holy spirit and pray that the lord send the comforter (Holy spirit) to you ,  if you have the Holy spirit, you will have His anointing right in you. The scripture says in 1 john 2:27 ’anointing ye have received of Him (Holy spirit)...’ that is; you can only receive the anointing through the Holy spirit. 

conclusion:

The anointing helps you to know all things. By the anointing of the Holy Spirit you will understand the words and teachings of the gospel better.
