The text of the Bible clearly outlines a plan of salvation which God has created for us. Some might ask why we would need such salvation, and the Bible covers that as well. All persons have sinned, young and old. As the Bible states, we have all come short of the glory of God. Simply put, we are born sinners. If you don't believe that, then ask yourself these questions:
1) Why is it natural for us to lie when we get in trouble?
2) Why is our first instinct usually to do wrong - to lie, cheat, or steal?
3) Why must we constantly struggle with ourselves to do right?
Once we acknowledge our nature, the important question becomes "What can I do about it?"
In the days of the Old Testament, sin was cleansed by ritual sacrifice. You would choose the best of your herds or crops and sacrifice it to the Lord on an altar. However, this was only a temporary fix. You would have to continuously make sacrifices for your sins. However, God ended this practice with a single, final sacrifice -- that of himself. He fashioned a body for himself, lived among us for thirty years as a perfect, sinless example, and then allowed us to torture him and painfully kill him. However, it didn't stop there. In fact, the most important part was yet to come. Three days after his physical death, Jesus was resurrected. It is through this resurrection and victory over death that mankind can be saved. Because of his death and resurrection here on Earth, we have the opportunity to have eternal life in Heaven - a life without death.
Now, some say that God's plan of salvation is open to interpretation. In fact, the reason there are so many denominations in the Christian church is because each denomination interprets it differently. There's no reason for disagreement, however - the Bible puts it into one tidy little paragraph for us:
Acts 2:37 - 39
37. Now when they heard this, they were pricked in their heart, and said unto Peter and to the rest of the apostles, Men and brethren, what shall we do?
38. Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost.
39. For the promise is unto you, and to your children, and to all that are afar off, even as many as the Lord our God shall call.
So, here's the plan outline:
