Having a relationship with a God who loves you. You see, God loves you and has provided everything so that you can have an eternal relationship with him. What does it cost you? Nothing. What did it cost Him? Everything. Sounds too good to be true? Read on.
Here is some bad news: We are ALL sinners - you, me, Billy Graham, Mother Theresa. " for ALL have sinned and fall short of the glory of God." (Romans 3:23). You see God is holy, that is sinless, perfect and cannot have a relationship with sinful people. It as if a chasm separates us from God. But wait, it gets worse: "For the wages of sin is death..." (Romans 6:23). It does not look good for us at this point, but Romans 6:23 goes on to say, "but the free gift of God is eternal life." OK, how does that work? How do I get that gift?
You don't have to DO anything - that's the point of a free gift, isn't it? " But God demonstrates His own love toward us, in that while we were yet sinners, Christ died for us." (Romans 5:8) You see, God sent His only son, Jesus Christ to die on the cross on our behalf, taking the penalty of our sin on himself. "For God so loved the world, that He gave His only begotten Son, that whoever believes in Him shall not perish, but have eternal life." As the graphic shows, the cross bridges the gap between sinful man and a holy God. Because Christ died for our sins, we can have a relationship with God.
If you believe that Jesus Christ, the Son of God, died for your sins and accept this gift by faith, you will have eternal life with God. "if you confess with your mouth Jesus as Lord, and believe in your heart that God raised Him from the dead, you will be saved;" (Romans 10:9)
But is this really a free gift? How can I know for sure? God has promised in His Word, The Bible, that we are saved by His grace - His free gift. "For by grace you have been saved through faith; and that not of yourselves, it is the gift of God; not as a result of works, so that no one may boast." (Ephesians 2:8-9)
Christian faith is not believing in something "spiritual" for which there is no evidence. It is not like believing in unicorns. On the contrary, we firmly believe that there is sufficient evidence to believe that the Bible is a true historical account, and that is also inspired by God. We can rely on it. This is like the faith we have when we sit on a chair, believing that it will support us.
