Because it is God who commanded light to shine out of darkness, who shined in our hearts to give the light of the knowledge of the glory of God in the face of Jesus Christ.2 Corinthians 4:6 (EMTV)
Where the light shines, darkness flees. Light and darkness cannot dwell together.
Therefore, can we have our hearts filled with the “light of the knowledge of the glory of God” if our thoughts are dwelling on the dark things of this world? I believe not. That is why the Lord commands to think on “whatsoever things are true, whatsoever things are honourable, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report” (Philippians 4:8 RV), which requires us to bring “every thought into captivity to the obedience of Christ” (2 Corinthians 10:5).
It takes diligent effort, in the strength of Christ, to accomplish this. I am still fighting this battle. I’m sure many of you are, too. We must win this battle in order to find true freedom in Christ and receive the fullness of His Spirit; for He cannot fill us if we still have trash piled up in our hearts.
I want to encourage you all, my brothers and sisters! We are promised full and complete victory so long as we dwell in Christ and have Christ dwelling in our hearts, for He has already won the victory in our behalf. Let’s claim this Bible promise together!
I can do all things in Christ who strengtheneth me.Philippians 4:13 (RV/Webster’s)
