But God demonstrates his own love for us in this: while we were still sinners, Christ died for us. - Romans 5:8.
Humanity is innately flawed. It is not the solution - we needed a divine saviour, and we got - Christ. He took the ultimate punishment for our trespasses; He bore the punishment for every sin we ever and will ever commit - He bore it all, He is God and He undeservingly bore it all. Thank God everyday for saving us, for being the shepherd to His sheep.
