It may be a habit or an attitude that is harmful, or a personal matter that turns people off. Someone wisely observed that you must talk to God about men before you talk to men about God. It is God the Holy Spirit that must quicken the soul before that person can ask Jesus Christ to be his Savior. It might be wise to have someone else join you in prayer for that person. Pray specifically for the person by name, and ask God to prepare the heart of that person.
Prayer is like preparing the soil to receive the seed.
It makes a difference in the way the seed, the Bible, is received. I would put a little arrow to show me which way to go in the Bible to find that verse. You see, I want the person I am talking to about the Lord to actually read the verse for themselves, so I would be looking at it upside down, and I would be turning pages in the opposite direction that I normally use. By having the verses highlighted, it makes it easier to locate the verse for the person to read. Very often, we share our testimony, our ideas, or an interesting story of someone s conversion.
