Psalm 100:2 KJV
[2]“Serve the LORD with gladness: Come before his presence with singing.”
Our words are meant to praise God in every situation of our lives. We should always come into the Lord's presence with praise on our lips, glorifying His name. We should get into the habit and train ourselves to only use positive words to worship Him. The same way we speak to one another (to our children, spouse, boss) with love and adoration - we should do the same with our praise to Jesus.
Try to be aware of what you say and how you say it. This way we will see the power of God move in a miraculous way. Let's ask the Lord to season our speech with sweet words. This will make our lives successful!
