For if you forgive men when they sin against you, your heavenly Father will also forgive you. But if you do not forgive men their sins, your Father will not forgive your sins.
Forgiveness is not just an apology; it is one of the many important connections between you and God. God wishes to bless you with new mercies every day, but if He meets you with a heart filled with a grudge or anger, completing that task may take longer. Today, stop delaying your blessings because of your pride not to apologize. Saying "I'm sorry" once is worth a lifetime of blessings from God.
