The best news in all the world to the “ungodly,” who grieve under the cloud of darkness and guilt, is the news that God, by faith alone, counts them as righteous
because of Christ. This is the rock where we stand when the dark clouds gather and the floods lick at our feet: justification is by grace alone (not mixed with our merit), through faith alone (not mixed with our works) on the basis of Christ alone (not mingling his righteousness with ours), to the glory of God alone (not ours).
[from When the Darkness will not Lift by John Piper]
but this isn’t our default condition. we are sinners. enemies of a Holy God. until we make that commitment. to repent of our sins and to accept what Christ did for us and to make Him the center of our lives.
a Christian isn’t a Christian because of his religion. but because he has Christ.
