The most important decision you'll ever make is how you're going to spend your life after death. If you died today are you 100% sure you'd go to Heaven? Did you know the Bible tells us we can be sure?
In I John 5:13 it says, "These things have I written unto you that believe on the name of the Son of God, that ye may know that ye have eternal life."
How can we know?
In Romans 3:23 it says, "For all have sinned and come short of the glory of God." Realize you aren't perfect and Heaven is. We've come short of God's glory.
In Romans 6:23 it says, "For the wages of sin is death..." Our payment for our wrong doing is death, and subsequently, hell. This verse goes on to say, "...but the gift of God is eternal life through Jesus Christ our Lord." Jesus died on the cross as a sacrifice, to pay the debt for our sins. He offers that sacrifice as a gift to us.
In Romans 10:13 it says, "For whosoever shall call upon the name of the Lord shall be saved." We have to ask him for that gift. Call on God and ask for his free gift of salvation. He is the way, the truth, and the life. No man comes to God, except through His Son.
If you've never done this then I encourage you to do it today. More than I want to uplift people who are hurting, more than I want a cure for cancer, I want you to know you have eternal life!
