Col. 3:16 “Let the word of Christ dwell in you richly in all wisdom.”
Ephesians 3:17 “That Christ may dwell in your hearts by faith.”
To dwell means to take up residence. Look at these verses above. We are to invite (let) the Word live in us richly. We invite Christ to take up residence in our hearts. We are not asking Him to drop by for a visit. We are asking Him to move in. When He does, He brings all the riches of the fullness of grace with Him, and the result is that our minds and hearts are taken up with Him.
But we need renewal. We need daily cleansing, daily indwelling, daily renewal. Just like our homes need constant cleaning and upkeep, so do our hearts. Our homes are subject to daily wear and tear as well as long-term decay. We have to stay on top of it, constantly cleaning and renewing, straightening and scrubbing. In the same way, our hearts are subject to daily distractions and disobedience. They need constant tidying, constant oversight, especially if Christ is residing in our hearts.
Daily renewal means seeking Him daily, keeping His residence in order. Renewal means asking His Holy Spirit to fill us and convict us of sin (which is like pointing out the garbage behind the fridge). Renewal enables us to live in a manner worthy of the One Who has taken up residence.
When you are cleaning your home, clean your heart at the same time. How tidy is your heart? Any bad smells coming out of the closet? Ask for renewal, daily renewal. Practice the presence of Christ. Live as though you really believe that He resides in your heart. Speak to Him when you are doing the dishes. Sing to Him as you drive your kids to school. Praise Him in the morning and at night. Let His Word dwell in you richly.
Put out the welcome mat. Invite Christ to take up residence in your heart by faith. Open wide the doors of your heart and welcome Him in. Then live as though He really has come. That is living by faith.
