“And most of the brothers, having become confident in the Lord by my imprisonment, are much more bold to speak the word without fear.” Paul says in Philippians 1:14. Paul had no fear when he spoke of the Lord. He did not fear death. He lived with the understanding that if death was the greatest thing man could do to him, then there was no fear in that because death was gain for him. If he died he was just furthering the gospel, so it did not matter.
You will find a sense of freedom when you live in this way. You will see that you will not have any fear when telling others about Christ if you live in such a way that shows you do not fear death. Death can be scary for anyone, especially when you are going through something like cancer or other ailments. We need to be able to see death as Paul saw it, not as an end, but as the reward.
When someone dies that had a personal relationship with the Lord, it is a blessing. Their loved ones are reassured that they lived a life devoted to the Lord and have now received their reward: eternity with Jesus. When someone dies without Jesus, it is absolutely devastating knowing that they are eternally separated from Christ. As Christians we need to see death as a reward for anyone that knows Christ and have a sense of urgency for those who do not know Him.
