Yes, I do believe that it is God's will sometimes that Christians be killed. You see, "Precious in the sight of the Lord are the death of his saints." Psalm 116:15 If God were to call you home via a terrorist attack, then that is a great way to go!!! And especially if they are after you for being a Christian!!!! "Blessed are ye, when men shall revile you, and persecute you, and shall say all manner of evil agianst you falsely for my sake. Rejoice, and be exceeding glad: for great is your reward in heaven: for so persecuted they the prophets which were before you." Matthew 5:11,12
You see, there is so much more to life than just life on this earth, there is an eternity waiting for us. If you are a Christian, then the eternity waiting for you is Heaven and all its splendor!!!! And why would you not want to go there if it were God's will for you??? However, if you are not a Christian, the eternity waiting for you is very bad...eternity in the Lake of Fire. I do not want that for you and neither does God. Please think about this.
If you are a Christian and are still afraid to die, then pray about it. Ask God to give you peace.....I'll be praying for you!!!
