Thirteenth Sunday after Trinity
Covenant and Grace
"The Old Testament dealt with the promises of God to the chosen people. Thereby God placed Himself in 'covenant' relation to Israel (berith). This relation, like the promises and the gifts of God to Israel, is always onesided. It is always God's covenant, not Israel's, and not a mutual agreement, not a suntheke. This promise and covenant indeed obligates Israel, and Israel assumes these obligations, but the covenant emanates entirely from God."
R. C. H. Lenski, The Interpretation of the Epistle to the Hebrews, Columbus: Lutheran Book Concern, 1938, p. 235. Hebrews 7:22;
"To be sure, Baptism is so great that if you turn from sins and appeal to the covenant of Baptism, your sins are forgiven. Only see to it--if you sin in this wicked and wanton manner by presuming on God's grace--that the judgment does not lay hold of you and forestall your turning back. And even if you then wanted to believe and trust in your Baptism, your trial might by God's decree, be so great that faith could not stand the strain. If they scarcely remain in the faith who do no sin or who fall because of sheer weakness, where will your brazen wickedness remain, which has challenged and mocked God's grace? Let us, therefore, walk with care and fear that we may hold fast the riches of God's grace with a firm faith and joyfully give thanks to His mercy forever and ever. Amen."

"And, in a word, it remains eternally true what the Son of God says, John 15:5: Without Me ye can do nothing. And Paul, Philippians 2:13: It is God which worketh in you both to will and to do of His good pleasure. To all godly Christians who feel and experience in their hearts a small spark or longing for divine grace and eternal salvation this precious passage is very comforting; for they know that God has kindled in their hearts this beginning of true godliness, and that He will further strengthen and help them in their great weakness to persevere in true faith unto the end."

"These treasures are offered us by the Holy Ghost in the promise of the holy Gospel; and faith alone is the only means by which we lay hold upon, accept, and apply, and appropriate them to ourselves. This faith is a gift of God, by which we truly learn to know Christ, our Redeemer, in the Word of the Gospel, and trust in Him, that for the sake of His obedience alone we have the forgiveness of sins by grace, are regarded as godly and righteous by God the Father, and are eternally saved."

"Moreover, neither contrition nor love or any other virtue, but faith alone is the sole means and instrument by which and through which we can receive and accept the grace of God, the merit of Christ, and the forgiveness of sins, which are offered to us in the promise of the Gospel."
