16 Therefore we do not lose heart. Even though our outward man (body) is perishing, yet the inward man is being renewed day by day. 17 For our light affliction, which is but for a moment, is working for us a far more exceeding and eternal weight of glory, 18 while we do not look at the things which are seen, but at the things which are not seen. For the things which are seen are temporary, but the things which are not seen are eternal"
(2 Corinthian 4:16-18).
This is of course not an easy thing to do, and it is something we often struggle with. God created us to live and as human beings we cling to life. It is only by the grace of God that we are able to give our life so that others may live. Please pray for the safety of the missionaries in Guatemala and for them to be bold and courageous and not live in fear. Also pray for this missionary that God will not only spare his life, but heal him completely.
