For the Lord disciplines the one he loves,
and chastises every son whom he receives.
Hebrews 12:6 ESV
Sometimes God’s love hurts. Love (real godly selfless love) is not all about making the other person feel better. Agape love is about the actual well-being of the other person. Therefore sometimes God lets us go through pain. This can be the result of our own actions or just something He has allowed into our lives to make us stronger.
If you have accepted Christ, then God is your Father. Like any good father; He wants you to be as successful as possible. Sometimes He must let you endure painful circumstances that shape you into who He made you to be. Don’t let the world or misguided Christians fool you. God disciplines and chastises you in love! Wouldn’t you rather have God’s discipline in love over the foolishness of the world?
