Hello beautiful ones!
Matthew 12:35-37 says,
According to Matthew 12:35, we are to only SPEAK GOOD THINGS, but the Scripture makes it clear that we can only SPEAK GOOD THINGS if our heart is good, for out of the superabundance of our hearts, our mouth speaks. That is why Proverbs 4:20-24 says,
Therefore what proceeds out of your heart comes out of your mouth!  
Proverbs 23:7 says,
If Satan can get us to think a certain way, our lives will follow it.  What you think determines what is in your heart.  Why? Because the entrance into my heart IS what I think.  Then, what I see, hear, and speak will overwhelm my heart, both positive and negative.  What is in my heart becomes my life.
I declare every morning, in the Name of Jesus, by the power of the Holy Spirit, that I will not let any corrupt communication (word) ever proceed out of my mouth, but only what is good for necessary edification that is may impart grace to the hearers. If I miss it, I do what 1 John 1:9 says,
Look at this amazing verse from Philippians 4:8 (MSG),
So, as we fill our minds with the Word of God, our hearts will begin to change, because Hebrews 4:12 says,
Once our hearts begin to change, our WORDS will begin to change. Words are wonderful when they are used in a good way. They can encourage, edify, and give confidence to the hearer. Proverbs 15:23 says,
The Scripture teaches us from Proverbs 18:21 (Amp),
Words are containers for power and we need to choose them carefully! According to James 3:7-8 (Amp), we cannot tame our tongue without the help of the Holy Spirit:
Our quality of life cannot rise about our own confession.  
I encourage you to say only what God says in His Word, to the best of your ability (your faith in God).
According to Hebrews 4:14, Jesus is the High Priest of our confession and this means He can only do what we are saying that lines up with His Word.  
Do you know how important it is to learn how to SPEAK GOOD THINGS, by speaking the Word of God, which is full of all GOOD THINGS?
I encourage you to say what God says - so speak His Word - not what our feelings, other people, or our circumstances are telling us.  When we say what He wants us to say, we are going to have what He wants us to have.  
Know this: CHANGING THE WAY YOU SPEAK WILL CHANGE YOUR HEART. So, I exhort you to,
"Father, I thank You for helping my readers SPEAK GOOD THINGS.  As they are quick to hear and slow to speak, you will heal relationships, restore lives, and help us to be overcomers in every area of our lives, in Jesus' Name, Amen."
SPEAKING GOOD THINGS,
