Certainly not. We are all sinners, and God (who can’t sin) loves us. As Paul wrote
God shows his love for us in that while we were still sinners, Christ died for us.
We are also called to show love to everyone, regardless of what they have done. Jesus said
Love your enemies, do good to those who hate you. (Luke 6:27)
Of course, that can be difficult to do in practice, but we must aim to follow Jesus’ example.
Loving sinners is not the same as loving sin. God said to his son Jesus
You have loved righteousness and hated wickedness. (Hebrews 1:9)
Similarly, the people of Ephesus were praised for hating sin. Jesus said to them
Yet this you have: you hate the works of the Nicolaitans, which I also hate. (Rev 2:6)
There is a saying “Love the sinner but hate the sin”. While this is not explicitly found in the Bible, the above verses show that it is a biblical idea.
