But the faith that God gave Abraham did not falter, as it never will, but grew: “[Abraham] did not waver in unbelief about the promise of God but was strengthened in faith, giving glory to God. He was fully convinced that what God promised he was also able to do” (Rom. 4:20-21 NET). Therefore, “In hope [Abraham] believed against hope.” Though his circumstances shouted hopelessness, Abraham had hope, not because he looked to himself and his faithfulness but because he looked to the One who promised.
Like Abraham, there is nothing in us or anything that we have done that would persuade God to bestow his saving grace upon us, but he has. It is only by his grace through faith in Christ that “we should be called children of God; and so we are” (1 John 3:1). And as God’s children, the life we live in the here and now we live by faith in the Son of God, who loved us and gave himself for us (Gal. 2:20). As sojourners and exiles we are faithful to preach this good news to ourselves and share it with others near and far, not living as those who have no hope, knowing like Abraham that by faith “our citizenship is in heaven” (Phil. 3:20). Though “here we have no lasting city,” by faith “we seek the city that is to come” (Heb. 13:14).
Love lived out in the Christian life is a beautiful thing, revealing not a boastful arrogance but a sacrificial love, not a life of works to find God’s favor but a display of God’s unmerited favor through loving others as Christ loved us. For it was for love that God the Father sent his Son; it was for love that God the Son atoned for sin; it is for love that God the Spirit conforms us to God’s perfect law. This our one God has done and is doing, not by a law of works but by the law of faith. And so, brothers and sisters-in-Christ, by faith and in love, “Let the one who boasts, boast in the Lord” (1 Cor. 1:31).
Where does this put us, those made in God’s image but fallen from grace, those saved not by works but by grace through God’s gift of faith? It puts us in a position not of self-exalting glory but of God-glorifying praise. As the Shorter Catechism beautifully states, “Man’s chief end is to glorify God, and to enjoy him forever” (Q. 1). Yes, for this we were created in God’s image, and for this reason we were redeemed, to glorify him. So, let us rejoice in this: Though we all fall short of God’s glory, we are saved by his grace to glorify him forever!
Consider the immediate reality of this eternal life! How we live now has meaning and significance. As R.C. Sproul said rightly, “Right now counts forever.”  And as Jesus is the Way, it is through him that we live this life. The way to eternal life and the way to live life are one in the same—through faith in the Son of God. This is why Paul could say, “the life I now live in the flesh I live by faith in the Son of God, who loved me and gave himself for me” (Gal. 2:20), and that “the righteousness of God is revealed from faith for faith, as it is written, ‘The righteous shall live by faith’” (Rom. 1:17).
The result is “the bond of peace” or “the bond which consists of peace,” (O’Brien, 280), meaning unity in the body is evidenced in peace. Such peace is telling of the peace that every Christian enjoys with God the Father through God the Son by God the Holy Spirit. Just as there is unity in God, so there should be unity in his body, as it is manifested in the local church.
As we see and taste the bread as the sinless, broken body of our Lord, as we see and taste the wine as the atoning blood of our Savior, our right response is praise, praise for deliverance.
When Christians realize that their citizenship is in heaven, they begin acting as responsible citizens of earth. They invest wisely in relationships because they know they’re eternal.
But know this, although Jesus’ last Passover became for us the Lord’s Supper, there will come a day when we will enjoy this meal of bread and wine in the physical presence of the Lord in our “Father’s kingdom.” Through the sacrifice of Christ’s body upon the cross, through his shed blood for our sins, by God’s grace through faith in our Lord Jesus Christ, we will feast together at “the marriage supper of the Lamb” (Rev. 19:9).
We abide in Christ through faith. We abide in Christ with prayer. And through faith with prayer we evidence our purpose, bearing the fruit of the kingdom of God for his glory.
