Public moralizing without identifying with the human condition will only be seen as self-righteous arrogance, an attitude which contributes to further separation and deepens the wounds within the land. Honest confession should be the foundation of all our peace-making efforts. This world is hopelessly snared in irreconcilable differences. The answer is no. Without Jesus it's impossible.
All successful relationships are trinitarian in nature.
If there are just two of you, prepare for pain. You, your friend, and Jesus. Two nations plus Jesus. Two genders plus Jesus. Least of all love.
