If the Bible were destroyed and only John 3:16 remained that would be enough to bring the whole world to salvation. We do not have to be a walking encyclopedia to be saved. When we understand and experience John 3:16 we have a passport to Heaven.
The cause of salvation is found in the words, “For God so loved the world ...” (John 3:16). Salvation does not begin in the life of man, but in the love of God. God’s love goes beyond all other love. Salvation is rooted and grounded in the love of God.
“... that He gave His only begotten Son ...” is the cost of salvation. For our bodies God gave the product of the soil, but for our souls He gave the blood of His only begotten Son. God was willing to pay that price to make salvation available to us. Salvation is expensive. While it is free, it is not cheap.
The condition of salvation is given in the words “that whosoever believeth in Him.” Salvation is within the reach of everyone. We are saved by faith. Our faith must be in Christ. We all need to be saved, because we have all sinned. Christ can forgive the past and also help us live in the future.
The consequences of salvation is that we “shall not perish, but have everlasting life.” Once you trust Christ, you have never ending spiritual life.
If the world will believe, there is enough in John 3:16 to save the world.
