Question:As a Christian, I know that we should be in God's word daily so that we can be able to share the gospel with others. What Scriptures should we memorize to share the gospel as well as to help ourselves when we become weak?
I've always found that the passages you put to use most are the ones easiest to memorize. "For everyone who partakes only of milk is unskilled in the word of righteousness, for he is a babe. But solid food belongs to those who are of full age, that is, those who by reason of use have their senses exercised to discern both good and evil" (Hebrews 5:13-14). So when someone asks me about a topic I don't know much about, I arrange a time to get back to them, and then I go and study the topic. When I return those verses are fresh in my mind.
Over time I find that many people have similar questions. So as I study something that I expect to come up frequently, I jot the topic, verse references and a brief note into those blank pages at the front and back of my Bibles. Then if there is a gap between need, I know where I can refresh my memory. Over time those verses become easy to recall. You can see one of my lists at: Quick Reference for Personal Workers.
You're won't ever have all answers ready for all questions in advance. One of the things I like about studying with others is that every time someone will ask me a question from an angle I had not thought of before. I have an easier time studying when I have a goal and purpose in mind. Too many people won't talk to others until they feel they can handle all problems. Few ever get to the point that they think they can talk to another person. The attitude is completely backwards! I know I don't know everything, so let's talk. I'll share what I know and when I don't I now have a focused need for additional study. Then I'm better prepared for the next person to whom I talk
