Why God loves us?

This short question is among the most profound questions ever asked. No human would ever be able to answer it sufficiently. One thing is certain, however. God does not love us because we are lovable or because we deserve His love. If anything, the opposite is true. The state of mankind since the fall is one of rebellion and disobedience. Jeremiah 17:9 describes man’s inner condition. Our innermost beings are so corrupted by sin that even we don’t realize the extent to which sin has tainted us



The heart is deceitful above all things,
and desperately wicked: who can know it?
Jeremiah 17:9
King James Version (KJV)

As it is written, There is none righteous, no, not one:
 There is none that understandeth, there is none that seeketh after God.
They are all gone out of the way, they are together become unprofitable;
there is none that doeth good, no, not one.
Romans 3:10-12
King James Version (KJV)

"God Is Love"

This is a profound statement. God doesn't just love, He is love. His nature and essence are love.

He that loveth not knoweth not God; for God is love.

1 John 4:8
King James Version (KJV)

And we have known and believed the love that God hath to us.
God is love; and he that dwelleth in love dwelleth in God,
and God in him.

1 John 4:16
King James Version (KJV)

Since it is God's essential nature to love, He demonstrates His love by lavishing it on undeserving people who are in rebellion against Him. God’s love is not a sentimental, romantic feeling. Rather, it is unconditional love, the love of self-sacrifice. He demonstrates this sacrificial love by sending His Son to the cross to pay the penalty for our sin ,by drawing us to Himself, by forgiving us of our rebellion against Him, and by sending His Holy Spirit to dwell within us, thereby enabling us to love as He loves. He did this in spite of the fact that we did not deserve it. "But God demonstrates His own love for us in this: While we were still sinners, Christ died for us" (Romans 5:8).

Herein is love, not that we loved God,
but that he loved us, and sent his Son to
be the propitiation for our sins.
1 John 4:10
King James Version (KJV)

No man can come to me, except the Father
 which hath sent me draw him: and I will
raise him up at the last day.
John 6:44
King James Version (KJV)

But God commendeth his love toward us,
in that, while we were yet sinners, Christ died for us.
Romans 5:8
King James Version (KJV)

God knows each of us individually and loves us personally.His love is unconditional and never ending to all Mankind.
He wants none to perish but all to come into a personal relationship with him through His Son Jesus Christ.It is this experiencing of God’s love that distinguishes Christianity from all other religions. Why does God love us?
It is because of who He is: 
"God is love."
