It is absolutely necessary for the believer to be filled with the Spirit and the Word. Complete sincerity and absolute desire are not enough. If he neglects either of God's provisions, a Christian cannot live a spiritual life.
Every morning, before doing anything else, I go to God alone in prayer. I make sure I am confessed up-todate, not living in any known sin, and I ask Him to fill me with His Holy Spirit. If I were to neglect being filled, I would not have the provision of divine power to walk in the Spirit. Walking in the Spirit keeps me from fulfilling the lust of the flesh (Galatians 5:16).
Then, I pray with my wife for family members, for Christians here and on the foreign field, for local pastors and leaders of different denominations, for the needs of the ministry, for our government, and for the unsaved.
With the filling of the Holy Spirit is God's provision of His Word. The continual entrance of the Word brings in light (Psalm 119:130). When we live in that light, God's Kingdom is operating in us.
