God loved us first
From the very beginning, God loved Mankind. He created a beautiful environment for us, He breathed His own life into us and He gave us dominion over the earth. Yet as we know, something happened; Adam and Eve rebelled against God and from that point forward they were at odds with Him. In the fullness of time, God sent His Son Jesus to repair that relationship that had been so badly damaged by rebellion in the Garden. God’s love was so great; He was willing for His only Son to die for the redemption of humanity.
For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life. John 3:16
It was just before the Passover Festival. Jesus knew that the hour had come for him to leave this world and go to the Father. Having loved his own who were in the world, he loved them to the end. John 13:1
But God demonstrates his own love for us in this: While we were still sinners, Christ died for us. Romans 5:8
But we ought always to thank God for you, brothers and sisters loved by the Lord, because God chose you as firstfruits to be saved through the sanctifying work of the Spirit and through belief in the truth. 2 Thessalonians 2:13
With this sampling of verses it becomes clear that God loved us first, before humanity had any cause to love God.
