The other women gave her some suggestions: don't call back immediately, but wait until both can process what happened. Wait a few days and then bring her a freshly-baked cake. Wait and then ask for the Holy Spirit to guide her in the words she chose. Pray for her daughter-in-law that she will open her heart to receive forgiveness.
In all of our suggestions the key word was waiting. When we have wronged someone we decided it's best not to offer an apology immediately but to wait until the moment seems right. Forgiveness doesn't happen instantly; it needs time and prayer, and it especially needs God's grace.
Have you asked for forgiveness from someone before they were ready to forgive? What did you do?
