Jesus did not give specific instructions for every situation we might encounter - instead he taught VALUES & PRINCIPALS that we can use to navigate our unique circumstances.
The Beatitudes (from Jesus' famous Sermon on the Mount) cover some of the principals that God values. These are very different from the things the world around us tells us are important.
Because our lives are so short (compared to eternity) having the right values to guide us is absolutely crucial.
Primary Text is Matthew 5:1-12
