What does it mean to say 'this is a day of good tidings'?

The phrase 'this is a day of good tidings' signifies the recognition of God's goodness and the responsibility to share that with others. The lepers in 2 Kings 7 understand that the miraculous provision they have found is not just for themselves but is a message to be communicated to those in need. This reflects a core tenet of faith—acknowledging God’s mercy shown to us and the imperative to share that revelation with others. Just as the lepers were compelled to act on the good news, believers today are encouraged to testify to God's grace and goodness, which ultimately brings glory to Him.
