"How do you tune your heart? There are at least three ways that the Bible suggests:
An open Bible in the presence of God. Beyond the sacred page, seek the living Word, the Rhema of God. As you are in the Scriptures and your heart is lifted, you’re brought into a growing agreement with the mind of God, renewed in the spirit of your mind, sanctified by the renewal of your mind. As you learn His thoughts and the mind of Christ shines through the Word of God and you hide that living Word in your heart, your heart is tuned to agree with God. Agreeing with God in a daily, deepening basis, is simply a deepening daily repentance, turning from your old way of thinking. It is an exchanged mind, the mind of Christ instead of the mind of this world and flesh which is all that we’ve ever had.
As more and more every day you come to the Lord with an unveiled face, beholding as in the Word of God the very face of the Lord Jesus, as you worship Him, you are being changed even by the Spirit of God into that same image that you behold in the mirror of the Word. As you see Him in His light you have light.
Secondly, time alone with God in prayer. It is not just reading His Word and having heaven open, but it is hearing His voice. It is trembling at His Word, hearing that holy resonation of the living God opening to us, the Holy Spirit taking the things of Christ and showing them to us. As you are in prayer, being still, holding your heart next to that throne room of God and knowing Him, your heart begins to tremble, and you are changed.
And a third thing: adjustment by godly saints. I need their fellowship and they need me. God will show something of what He is like through other saints, and by His Spirit will adjust my heart to agree with that reality. We see the blending of His heavenly will and the sharing of His heart and sympathy as we gather together in His name. When there is honest communication and a meeting together at the throne of God, the power of His presence is released in our lives corporately. How clearly this is seen in those first chapters of Acts.
I must decrease that Christ might increase. And it’s the old, precious cross taken, not just a cross but the cross. It is no longer I but Christ. The cross as revealed to me—a sinner is pardoned; the cross revealed in me—the saint is purified; the cross revealed through me—the Saviour is proclaimed to a world that has no answers except the one He has put in your heart as a stewardship. You have to have the throne room of the Lamb there.
The Lord wants to raise our perspective to His. He wants us to sing and make melody in our hearts. Too many of us have lost that great wonder and astonishment and the awe that I think is the fear of the Lord, a sensing of who He is in the holiness of His presence. Do words like wonder, and astonishment, and amazement, and admiration, and fascination describe our worship?
If we have lost touch with the throne room of God, might the Lord tune our hearts by time alone in His Word. Might He open the Scriptures to us. Our hearts will begin to burn as we take the page and He shows to us the Lord Jesus Christ. When was the last time you were totally amazed alone, in the presence of God? You didn’t have any words. All you could do was just be in awe. Has it happened to you recently? We’re supposed to live there. We’re supposed to live in that holy presence. Until we are in the real and permanent throne room of God, we need to get a vision, a revelation like Isaiah, of the Lord Jesus high and lifted up."
