They read from the Book of the Law of God, making it clear and giving the meaning so that the people understood what was being read. Nehemiah 8:8 The Holy Bible Amplified Version
There are two important parts to this verse.
The first part I would call keep it simple. Do not use big words or go into big philosophical debates with them. Just share the Message with them. A majority of times they are most impressed with you sharing what Christ has done in your life and through your life. That makes Him real to them.
The second part is to explain what the Bible verse or verses meant to the folks in that culture and in that time so that there is deeper understanding.
So many times I have encountered Christians that quote a Bible verse however when questioned on its meaning in the context of the time and culture they have no idea which makes them appear rather stupid.
Before you go sharing the Message do your homework so you are prepared. This does not take a few days or week but years. Look how long it took Paul before He began teaching (I believe it was two years).
Before you go sharing the Bible, learn it and live it. Joseph a son of Jehovah
Prayer: Please Jehovah El Deah (God of knowledge.) bless me with the knowledge on how to deliver the Message in a clear simple manner in which the soul in which it is being delivered to can understand it and have a thirst for me and a yearning to become a Holy child of Yours.
Please bless me with the knowledge in understanding when those who are not receptive to receiving Your loving Message so as to not waste my valuable time while being respectful towards them.
I humbly ask this in the name of the greatest deliverer of the Message Jesus Christ. Amen.
May Gods sunshine always bless you with brightening your day with His love, joy and peace. Joseph a son of Jehovah
