“Everything needed for continual growth, for perpetual freshness, and for abundant fruitfulness are found in Him [Lord Jesus]. All power, all grace, all purity, and all fullness, absolutely everything to make all grace abound towards us, in us, and through us, are stored up in Him who verily dwells with us.
Since this is so, what then is needed? Shall we try to help Christ to live in us? shall we try to make Christ more living? shall we help Him to put forth His own power in us? shall we try, in other words, to grow—to produce fruit? Surely not. And yet is not this the grand mistake multitudes are making? Something however has to be done. Something is needed to deepen our spiritual life. All Christians have Christ, and possess therefore all the resources of spiritual power and abundant fruitfulness; and yet all Christians are not abounding in fruit unto God. What is the reason of this?
It is here: though we cannot make Christ more living, though we cannot add to His infinite fullness of life and purity and power, we may be hindering the manifestation of that life.
One of the most serious hindrances is unbelief. This lies at the root of every other hindrance.”

Your body is literally the temple of the Holy Spirit (1 Corinthians 6:19). Dwelling in your body as a Christian is not only your unique personality but also the Spirit of Jesus Christ who is a living Person. What God wants you to be only the Lord Jesus in you can be. He merely asks for you to be wholly available to Him with complete submission and to trust Him without any doubting. This way He can shine through you! Trust Him!

Without faith it is impossible to please him.
