There are days when I feel that it's important to remind you why you're saved at this particular time. God could have left you to wallow in your sin until right before your very last breath, but He chose to save you now for a reason. We have no need to fear "the day of the Lord". We will be caught up before the impending wrath of God takes place. But, if you want a sobering reminder as to why we need to evangelize and bring others into the saving knowledge of Christ, just do a quick search on the internet for "the day of the Lord". The wrath of God is not something we should take lightly. If you think that what's going on now is bad, just take a look at what's looming for those who do not know or have rejected our Savior. The devastation and the eternity that awaits them is quite overwhelming. If you truly have the heart of Jesus then you will want to save them from that wrath by telling them about Him.
For us: And night will be no more. They will need no light of lamp or sun, for the Lord God will be their light, and they will reign forever and ever. Revelation 22:5
For Them: I will bring distress on mankind, so that they shall walk like the blind, because they have sinned against the LORD; their blood shall be poured out like dust, and their flesh like dung. Zephaniah 1:17
