John 3: 16: “For God so loved the world that he sent his one and only Son, that whoever believes in him shall not perish but have eternal life.”
God so loved the world. He didn’t just love the world; He so loved the world. He so loved the world that He (Jesus) would die in our place before He would miss out on an eternal relationship with us. He knew that we would disappoint Him and hurt Him and fail Him, but He still so wanted a relationship with us that He made a way. He knew that there would be many, many people that would reject His gift of love and salvation, but an eternity spent with those who would choose Him was worth the price of dying on the cross. That is some amazing love!
Because this will be what matters most the moment after you die. And, quite honestly, it's what matters most in this lifetime, too.
