Jesus tells us that once he leaves he would send us a helper (The Holy Spirit) to help continue to guide us and teach us. This is our first point of contact to the Spiritual World.
I believe that we should pray to the Holy Spirit before picking up the Bible for the understanding (interpretation) of God's word. (Bible)
If it is done this way; the knowledge gained will turn into wisdom and God's grace and annointing will be on you and you will be guided to do God's purpose over your life - which will surely please Father God, Jesus and make your life better in ways you can not imagine.
In addition, I believe that it is not not meant to just pick it up and read it and decide on what is meant. The enemy knows the Bible well and can manipulate thinking so to understand what has been read is not meant that way or to confuse you all together.
This form of manipulation of thought will serve as a seed and root into your mind where it will be nurtured from evil until a product is produced with the mission to have you on the path of lack, self-destruction and on to your death.
We need to be respectful and careful with such powerful information. As everything you will ever need to know is in the Bible.
Some religious groups make it a practice to bath/shower their bodies all over and inside and out including (i.e., inside of ears, mouth and all other parts thoroughly) in prepraration to speak with Jesus. They ask the Holy Spirit to be reminded of any sins or disappointments that they may have caused God - the ones they remember and the ones they do not- so they can ask for forgiveness and repent before they go into Jesus Christ in prayer.
The goal is have a clean mind, body and soul (heart) before going to the Throne of Jesus and in my opinion shows great honor and respect to Jesus. Since he is pure and holy - we too need to be as pure and holy as we can be so we may be able to connect to Jesus Christ and our prayers are welcomed by him and discussed with the Father in Heaven on our behalf.
I know the Bible says come as you are - no need for these types of formalities to go to Jesus in prayer. This is my opinion and how I choose to serve my Lord and Savior.
