The above verse is the bridegroom speaking. The church's Bridegroom is Jesus andHe wants to hear us.
And He means verbally.
Okay, so not everyone is a shouter. Not everyone gets loud when praising. God gave us all different personalities to express our love for Him in our own ways.
Yet, if you can get enthusiastic about anything, than you can get enthusisastic and filled with joy about Jesus.
Let Him hear you say you love Him today. Let Him hear you speak to Him with your voice. Sing Happy Birthday to Him. Love Him with your voice today.
