May the words of my mouth and the meditation of my heart be pleasing in your sight, O Lord, my Rock and my Redeemer (Psalm 19:14 NIV).
Words can encourage. It can also discourage. Words can heal. It can also wound. Words can foster friendship. It can also cause enmity. Therefore words have to be chosen carefully while speaking. Or else harm that was never intended would result from the speaking of careless words.
If words should be spoken with care in front of men, how much more should we take care when speaking before God. In fact, whatever we speak is heard by God. This is a solemn thought. If we are conscious of this fact, we will take care to speak thoughtfully and not use unnecessary and careless words. Then our words would bring healing, comfort, joy and encouragement to the one who listens.
The mouth can only speak what the heart thinks. In the silence of our hearts we think and meditate. Meditation implies deep thought. Even though no man can hear what our meditations are, it is audible to God since He searches our hearts and nothing is hidden before Him.
David here prays that both his speech and innermost thoughts be pleasing in God’s sight. Only if our intention is to please God at all times can our speech and thought be clean and without sin. This is a difficult task. For we often forget that we belong to our Redeemer. And we think very bad thoughts and speak without any restraint. Let us take care to remember that God is our Rock. He is almighty. Let us fear Him and be pleasing to Him in thought and speech.
