The threat to Christian assurance

19This is how we know that we belong to the truth and how we set our hearts at rest in his presence: 20if our hearts condemn us, we know that God is greater than our hearts, and he knows everything. 21Dear friends, if our hearts do not condemn us, we have confidence before God 22and receive from him anything we ask, because we keep his commands and do what pleases him. 23And this is his command: to believe in the name of his Son, Jesus Christ, and to love one another as he commanded us. 24The one who keeps God’s commands lives in him, and he in them. And this is how we know that he lives in us: we know it by the Spirit he gave us.
