The fact that I can know NOW that I have Salvation in Christ brings a peace that the world itself can't give. I don't have to go through life wondering weather or not I have done everything I need to do so that I may have eternal life in heaven. I can rest in Christ, in peace knowing that soon, one day, in the blink of an eye, I will be resting in the arms of the father, never leaving His presence. What a joyous feeling it is, so much so that my words lack the ability to show my thankfulness! I wish for the world to know how great it is and and great it could be for them as well (if they don't yet know it).
