So it is with Gods people today. We are called to attend to the altar of our hearts continually and to never let the worship fire go out. Still most Christians today have grown content to surrender this passion for a lintany of lesser things (Luke 14:16-20) and so we find God people very cold despite the fact they they may be involved in a host of ministries both within and without the church.
The fuel so desperately needed today is that which comes from heart consumned with and constrained by a vision of God high and lifted up (Psalm 63:1-8). When we set our minds eye upon His supremacy, centrality and all sufficency and we linger in that glory we will begin to see the dross of other things melt away. As this coldness retreats will will find ourselves longing for even greater fire and greater love for Christ and before we know it we will enter that fellowship of a burning heart.
The key is time meditating on the wonder and the glory and the Person of God (Isaiah 26:9). We must give ourselves to it if we are to experience this fire burning intensly on the altars of our hearts. Give yourselves to that which you were called to and end your love affair with the world and soon you will feel deep within your soul that fire that brightens and burns for the glory of God.
