Before the Divine Service O Lord, our Creator, Redeemer, and Comforter, as we come together to worship You in spirit and in truth, we humbly pray that You may open our hearts to the preaching of Your Word, so that we may repent of our sins, believe in Jesus Christ as our only Saviour, and grow in grace and holiness. Hear us for His sake. Amen.
After the Divine Service Almighty and merciful God, we have again worshiped in Your presence and have received forgiveness for our many sins and the assurance of Your love in Jesus Christ. We thank You for this undeserved grace and ask You to keep us in faith until we inherit eternal salvation; through Jesus Christ, our Lord. Amen.
Before Receiving the Lord’s Supper Heavenly Father, I confess that I have sinned and deserved only Your wrath, but I flee to Your mercy in Christ Jesus, my Lord, who gave His body and blood for my redemption. I believe that Jesus Christ has redeemed me from all my sins, and I desire forgiveness in His name. I intend with the help of the Holy Spirit to live as in Your presence, and to strive daily to lead a holy life, even as Christ has made me holy. Lord, grant that I may ever thus believe and never waver. Grant that in such faith I may worthily go to Your altar to receive the very body and the true blood which Your Son has given for my salvation, that I may truly praise, laud, and honour Your love and Your mercy all the days of my life. Hear me for the sake of Jesus Christ, Your Son, my Redeemer and Saviour. Amen.
After Receiving the Lord’s Supper O Lord Jesus, my Saviour and only Refuge, I give You hearty thanks that You have so graciously refreshed me with Your sacred body and blood, and I pray that through this Holy Supper You would strengthen me in faith toward You, in love toward others, in patience under trials, and in the blessed hope of everlasting life. Uphold me daily with Your grace and strengthen me by Your power. Into Your hands I commit my body and soul, in life and in death. Grant that, when my last hour comes, I may fall asleep in firm faith in You and Your sacred blood. Amen.

† Lord Jesus, I believe. Help my Unbelief! †
Lord Jesus, I believe. Help my unbelief! Strengthen my weak and flickering faith. I know that You are my wisdom, my righteousness, my sanctification, and my redemption. Lord, strengthen this faith in me, that I may never fear nor faint in any trial or temptation. You alone are the Author and Finisher of my faith. Though my faith be tried with fire, may I ever be found strong and unmovable to the glory of Your holy name. Let me firmly trust in Your blood, which cleanses me from all sin, that though my sins are as scarlet, they shall be as white as snow. When I am enticed by sin and the world beckons and my own passions want to yield, help my unbelief, and give me the strength and will to resist. When trials, sorrow, and affliction want to rob me of this trust, O Lord, help me to remain steadfast and true. Strengthen my faith in Your promise that all things work together for good to them that love God, to them that are called according to Your purpose to be Your own here in time and there in eternity. You, O almighty Lord, can help; You, O gracious Lord, will help my unbelief; You, O merciful Lord, will strengthen my faith. Lord, I believe!. Amen.

† A Prayer for Living in One’s Baptism †
In Holy Baptism, O triune God, You entered into my heart and made it Your temple and dwelling-place. Keep me always mindful of this high distinction. Whenever Satan seeks to seduce me to sin, to neglect Your Word and will, to dishonesty, selfishness, and envy, help me to resist him in Your strength, to beat back his attacks and obtain the victory. Father in heaven, let me never forget that I am Your child and that Satan’s only purpose is to separate me from You. O Saviour, Jesus Christ, keep Your bitter suffering ever before me, so that I hate and abhor every sin, no matter how small it may seem. O Holy Spirit, who has regenerated me, keep me in this newness of life, and let not Satan lure me back into the way that leads to eternal damnation. Triune God, keep me constant in Your means of grace—the Word and Sacraments—that in the power of Your might I may be able to withstand in the evil day and, having done all, to stand. Hear me, for Jesus’ sake. Amen.

† A Prayer in Remembrance of Holy Baptism †
Dear Father in heaven, You have adopted me as Your very own and given me Your name in the waters of my Holy Baptism. You have generously poured out upon me Your Holy Spirit through Your Son, my only Saviour, Jesus Christ. By the washing of the water with Your Word, I have been united with Him in His death. Just as surely do I have a share in His resurrection and His never-ending life. For His sake You have called me a beloved child and declared me to be well-pleasing in Your sight. For all of this I thank and praise You.

Yet, my old Adam remains, with all my sinful desires, while the devil and the world seek to entice me away from You. Only You can help me and save me. Be gracious to me; guard and protect me from all evil. Surround me with Your holy angels; keep the devil at bay, and all his works and all his ways far from me. Return me always to the saving waters of my Holy Baptism, and thereby drown and destroy the old Adam within me. By Your Word and Holy Spirit, bring me daily to contrition and repentance, and by Your free and full forgiveness of my sins, strengthen and sustain my faith and lift me up with Your dear Son to that new life that shows forth Your praise; through the same Jesus Christ, my Lord. Amen.
