Any worship I give is to Jehovah. So when I am sharing the Bible's message with others, whether relatives, neighbors, bankers, grocers, or doctors, etc, I feel I am offering the praise to Jehovah. He desires that we worship Him and bring glory to Him by fulfilling His desires. He does not desire any to lose their life, and if I have just a small, even miniscule opportunity to direct a persons attention to their Heavenly Father and Creator, I feel that I am one of God's co-workers that the apostle Paul referred to.
I do not feel that my soul depends on knocking on doors. First I am a soul. Second, my eternal life depends on the sacrifice of Jesus Christ that Jehovah provided. That is a free gift for all to accept and show appreciation for through prayer, study and praise..
