Psa 49:3
My mouth will speak wisdom,
And the meditation of my heart will be understanding.

Psa 105:2
Sing to Him, sing praises to Him;
Speak of all His wonders.

Psa 119:46
I will also speak of Your testimonies before kings
And shall not be ashamed.

Do you speak wisdom?
Does your heart understand?
Do you sing praises to Him?
Do you speak of all His wonders?
Do you speak of His testimonies before “the powers that be”?
Do you speak without shame?

Psa 145:6
Men shall speak of the power of Your awesome acts,
And I will tell of Your greatness.

Psa 145:11
They shall speak of the glory of Your kingdom
And talk of Your power;

Psa 145:21
My mouth will speak the praise of the LORD,
And all flesh will bless His holy name forever and ever.

Tell of His greatness.
Speak of His glory.
Talk of His power.
Speak of His praise.
Bless His name.

If you do not, the very rocks will cry out.
If there is no desire to do such, then examine yourself to see if you are of the faith.
