The intending communicant needs to be reminded of the greatness of our God. Because of God's holiness we must have clean hands, a pure heart, and a soul that is not occupied with idols, and a clean tongue in order to approach Him acceptably. Thankfully, in the gospel God has made provision for us in our justification through the merits of Christ. Before partaking in Communion, the believer has a duty to seek the Lord, cleansing our hands and purifying our hearts so as to worship him acceptably.
