What does it mean that God has a plan for believers?

According to Ephesians 2:10, believers are God's workmanship, created in Christ Jesus for good works that He prepared in advance for us. This indicates that God has a specific plan for each believer, encompassing our journey of sanctification, where we grow in holiness and reflect Christ's character. The end goal of this plan includes our glorification, as noted in Romans 8:29-30, where those whom He predestined are called, justified, and ultimately glorified. God's sovereign grace operates throughout this process, ensuring that all things work together for the good of those who love Him.
