I refuse to have my last emotion be anger.
Ever had bad blood between a brother or sister? My end goal when I have an issue with a brother or sister is not to see them get their just desserts, but rather to work with them as effective teammates, truly able to rejoice and love one another, embracing over successes in Christ, for Christ.
"Let no debt remain outstanding, except the continuing debt to love one another, for he who loves his neighbor has fulfilled the law." (Rom 13:8)
When I die, even if someone detests me, I want to die having a love for them. I can never control how someone feels about me, but I can control one thing: leaving only a debt of love. No bitterness or malice will exist in heaven, and I don't want to try and bring any of that along with me.
