After telling his disciples that they should love one another, Jesus began preparing them in John 15:18-16:11 to be hated by the world. Even so, he sent them out to be witnesses for him, but not on their own. He also promised to send the Holy Spirit to be the witness who would convince the world about the truth of the gospel.
Faith is the means by which we are saved, obey God, and forgive our brothers and sisters.
No matter how bad things get, God is still working out his own holy will through seen and unseen agents.
Because humans were dead in our sins, the only possible solution was for God to make us alive because of his grace.
