Christians, why does God Love the whole world, when the whole world is so sinful?

For God demonstrated his love toward us in that while we were still sinners Christ died for us.

And God said I do not take any delight in the death of the wicked Man instead I desire every person to come to repentance and receive everlasting life.

When you have a child and that child is truly rotten and goes out and gets himself in trouble and goes to jail in prison. You might not like that child very much as a person but you still love the child as a parent.

And you wish with all your heart you could do something to make the child change.  You can provide the money and everything that that child needs but sometimes that child never changes.

The same holds true with us as human beings we are all the sons and daughters of the most high God.

God might not be happy with our actions but God loves us as a parent would love a rotten kid.

Our spirits are literally his children.  He loves us more than we can imagine.  He doesn't approve of the way the world is, and he may yet have to take drastic measures to reform our society.

God does not love the sin, but He does love us.

God wants us to repent and to love and follow Him.

It's because Jesus is a God of love. It's part of His nature. God loves sinners even though He hates our sin.

The Bible is very clear that no one can earn their way to heaven since good works do not pay for sins. See Gal. 2:16, Rom. 3:23-28, 4:4-5, Eph. 2:8-9, Tit. 3:5. The only way to heaven is by believing in Jesus for His free gift of eternal life. Jesus shed His blood on the cross as the full payment for our sins. He did all the work; all He requires of us is that we believe in Him. Once you believe in Jesus Christ to save you, you are secure forever!

Because we have all sinned against a perfectly holy and righteous God, we all deserve eternal separation from God in hell (Rom. 6:23). However, God loves us so much that He sent His only Son Jesus to die on the cross as our Substitute so we don't have to go to hell. Christ died for our sins, was buried, and rose from the grave three days later (1 Cor. 15:3-4). He gives eternal life freely to anyone who simply believes in Him for it. No one can be saved by doing good works. Salvation is by grace alone through faith alone in Christ alone (Eph. 2:8-9).

"Verily, verily, I say unto you, He that believeth on me hath everlasting life" (John 6:47).

We inherited sin from Adam and Eve. But because God loves us he sent his only begotten son to die for us , so that we can repent and be forgiven. 

1 John 4:9- 'By this the love of God was revealed in our case, that God sent his only-begotten Son into the world so that we might gain life through him.'

John 3 [16] For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
