I have two brothers in Christ who have mentioned with fondness that they own Bibles that belonged to a grandmother. The fact that their Grandma used that Bible and made heartfelt notes in it is clearly what brings added treasure as these men read those Bibles. It is a heart connection with someone they loved and who is now with the Lord. “I will make thy name to be remembered in all generations: therefore shall the people praise thee for ever and ever.” (Psalms 45:17).

Please consider doing something similar for those you love. It is a parting gift for when you go to be with the Lord. Here are some practical suggestions for this.

Purchase quality Bibles so they will last through many years of use. My preferred publishers are Cambridge and Schuyler. Choose a Bible that is Smythe sewn, has quality paper, and is real leather (goatskin even). Select large type so it is not hard to read. 

Underline key verses that speak to your heart. I use different colors: red for commands, blue reveals God, black for general special emphasis, and green for salvation related. Set up a legend that works for you. 

I use Pigma Micron pens, .25 mm for notes and .45 mm to underline boldly, or .25 mm less bold. Westcott (#18) makes a 6 inch flexible plastic ruler that is perfect for underlining. It will conform to the page shape, isn’t too long to get in the way, and goes margin to margin. I get mine at Hobby Lobby. 

During my early years of Bible reading, I tried highlighters, but they looked messy, even though I tried to be neat. It’s God’s Word, and I want my Bibles to be treasured. “It is written, Man shall not live by bread alone, but by every word that proceedeth out of the mouth of God” (Matthew 4:4).
