Our hearts betray Jesus because we are selfish, sinful, and broken, and there’s nothing we can do on our own to change that. We have all betrayed Jesus through sin and rebellion. Christ died for the sake of sinners, so that we could be redeemed and be ready for his return. If we trust in his work for our salvation (his body and blood) instead of our work for salvation, he will redeem us, heal us, and fit us for his coming Kingdom.
