She shall bring forth a son, and thou shalt call his name JESUS: for he shall save his people from their sins. (Matthew 1:21)
Call His name: JESUS. Call Him when you are sad, scared, angry, alone, tempted. Call Him when you are happy, celebrating, thankful, strong in your faith, in a crowd. Call Him whenever. Call Him more often. Call Him tenderly, prayerfully, powerfully. Call on Him and know that He will answer, no matter what.
