I am asked occasionally how to increase one's motivation to read the Bible. I council in this regard, it is necessary to think of the negative in order to achieve the positive.
First, you ought to feel guilty for not reading God’s word. The greatest indignity man can inflict upon his creator is not to listen when He speaks. The Bible is God speaking. God puts his word above his name which makes His word the most important of all things in creation. One should read it to the best of their ability. You will never understand any of it unless you know what it says.
If the knowledge of the Bible is insufficient to be able to point to what God said as the reason you live your life the way you do, you are sinning against God continually. If we just do what we think is right, we are glorify ourselves and not God. Explaining that you live so because God said so glorifies God.
Proverbs 3:6 In all thy ways acknowledge him, and he shall direct thy paths.
1 Corinthians 10:31 Whether therefore ye eat, or drink, or whatsoever ye do, do all to the glory of God.
If you do not know your Bible you will be weak in the faith and knowledge of God being unable to witness effectively. You probably will not witness at all as no one likes to be embarrassed by questions they cannot answer. Your lack of witness will cost others their souls.
For the want of a shoe the horse was lost,
For the want of a horse the rider was lost,
For the want of a rider the battle was lost,
For the want of a battle the kingdom was lost,
And all for the want of a horseshoe-nail.”
How many millions souls will be lost because we did not know our Bible?
For the want of our knowing the Scriptures, our faithfulness was lost,
For want of our faithfulness, our witness was lost,
For the want of our witness, the truth was lost,
For the want of the truth, others were lost,
All for the want of us knowing God's word.
Thinking of the negative results of your not reading and knowing the Scriptures may spur you on to being more faithful in doing so. It may be your children or grandchildren or other loved one that is lost for the want of you doing so.
To obtain the positive consider the negative. If you would like more incentive and help in understanding the Bible, I recommend the following which I know is good because I wrote it.
Please, if you have trusted in the Lord Jesus Christ, read the Bible!
