1 John 4:16
And we have known and believed the love that God has for us. God is love, and he who abides in love abides in God, and God in him.
For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life.
1 John 4:10
In this is love, not that we loved God, but that He loved us and sent His Son to be the propitiation (sacrifice) for our sins.
1 John 4:19
We love Him because He first loved us.
Romans 5:5-9 New Living Translation
And this hope will not lead to disappointment. For we know how dearly God loves us, because he has given us the Holy Spirit to fill our hearts with his love. When we were utterly helpless, Christ came at just the right time and died for us sinners. Now, most people would not be willing to die for an upright person, though someone might perhaps be willing to die for a person who is especially good. But God showed his great love for us by sending Christ to die for us while we were still sinners. And since we have been made right in God’s sight by the blood of Christ, he will certainly save us from God’s condemnation.
