I ask the Lord to let me evangelize to as many people as possible, and the opportunities often come up, and the right moment to say something follows too. People commonly talk about their worldly problems. At the appropriate moment, I would let my listeners know outright that what I am going to say to them, most likely they won't hear from another person. I tell them that my main concern for them are not worldly problems but eternal life, which must be considered foremost. Then I present Jesus as our answer. My listeners always seem to understand my intention and that I speak it out of love. So a seed is sown and may bear fruit one day.
