Romans 14:8 For whether we live, we live unto the Lord; and whether we die, we die unto the Lord: whether we live therefore, or die, we are the Lord's.

When we are in Christ, we truly have nothing to fear or worry about because God always ensures things will work out for our good. When we live, we live to carry out work for God – evangelizing, ministering, helping those in need, etc. When we die, we don't lose. We return to our heavenly home, awaiting the day Christ returns to the world. As Christians, we have no reason to fear death because we know what waits for us on the other side – our hope remains valid.
