True Christians pray for one another, especially for victory over sin.
Those who truly know God’s love in Christ purify themselves in Him.
When you obey Christ, you testify that Christ has truly saved you; when you sin, your claim to be a Christian is undermined.
To love God above all else is right. Whenever we fail to love God above someone or something else we sin.
Followers of Jesus are to live as strangers in this world. We must refuse to go along with sin and insist on doing what is right and good.
