Let the words of my mouth, and the meditation of my heart, be acceptable in thy sight, O LORD, my strength, and my redeemer.
It is one thing to be diligent of our words, which others around us can hear and know about, but another to be diligent about the thoughts of our hearts and minds that only we and God know about. Sometimes it is those things in our secret places that we let ourselves get away with more easily. So we have to be disciplined in our thought life, where there is no one to keep us accountable except ourselves and God. We cannot fool ourselves into thinking that we can get away with things just because no one else knows about them, because God knows every thought we have.
What can we do to make sure that everything that comes out of us and everything within us is pleasing to the Lord? One way is to submit to the leading of the Holy Spirit. He is with us to be our guide and to lead us in the things that are pleasing to God. And if we are sensitive to His prodding, He will let us know when the things we meditate on are displeasing to the Lord. He will search and try the things that we keep inside our hearts and reveal to us things that are there that shouldn’t be.
We also need to gauge things by the Word of God. There are countless warnings in Scripture about things we need to stay away from. And if our minds are focused on the things of the Lord, the words that He’s given to us, we can be sure that we are focusing on the right things. We’re supposed to be meditating on God’s Word, so if our mind drifts somewhere we think it shouldn’t, we can remind ourselves of a favorite verse or sing a hymn to help refocus our mind on God.
No matter what kinds of questions we have or issues that come up, we can always just talk to God about them. When we go to Him in prayer with sincere questions or doubts, He can lead us into His truth. When we express ourselves to Him in earnest prayer, He will respond to us in some way. And if we’re abiding in prayer to our Father, we can guard our minds from wandering down darkened paths of evil thoughts. May it be our prayer along with David that all we say and all we think on is acceptable to our Lord.
