Westminster Confession 3:6
As God has appointed the elect to glory, so he has—by the eternal and most free purpose of his will—foreordained all the means to that end. Therefore, his chosen ones, all of them being fallen in Adam, are redeemed by Christ and are effectually called to faith in Christ by his Spirit working in due season. They are justified, adopted, sanctified, and kept by his power, through faith, unto salvation. No others are redeemed by Christ, effectually called, justified, adopted, sanctified, and saved, except the elect only.
A personal God has selected individual persons to enter into his glory. That is salvation. He has not only chosen the end but also all the means to that end. We too often focus on the destination and not the journey. Glory begins the moment you are united to Christ by faith. We are called by the means of grace, (the gospel and the sacraments), we are cleansed from sin and made righteous by faith, we are accepted into his family and made progressively righteous by the Spirit of God. God has planned not only heaven, but also every step that leads in that direction. Your Christian parents, your 5th grade Sunday School teacher, your best friend’s conversion, your pastor's publishing of the gospel, your camp counselor, your favorite Christian book, and your devotional exercises all lead you to glory. We need to see the plan from the beginning to the end and not simply the end.
Each Christian’s story is remarkably different, and yet notably the same. We pass the same landmarks on the road of salvation. The burden and the sorrow of sin, the failure of our own efforts to ease its guilt and shame; the astonished joy at the freedom, power, and grace of the gospel; the bewildering acceptance that we enjoy as God’s own sons and daughter; the gradual and discernible nature of our growth in grace; and our future welcome into full, undiluted presence of God. These things mark the people of God. God’s work of salvation is tangible and evident for those who have the eyes to see. Since God has begun a good work in your, he will also carry it to completion. You are safe in his hands.
