All of us have experienced betrayals in our lives wherein somebody did not keep a promise or otherwise violated our trust. When God calls us to be trusting people, He knows that many will betray us, but that does not give us a license to refuse to trust anyone in the future. (what about them?!). May we ask God to give us good discernment when it comes to trusting others and to equip us to be trustworthy people ourselves.
