'Purpose' in the Bible

We know that all things work together for the good of those who love God: those who are called according to His purpose.

For though her sons had not been born yet or done anything good or bad, so that God’s purpose according to election might stand—

to be a minister of Christ Jesus to the Gentiles, serving as a priest of God’s good news. My purpose is that the offering of the Gentiles may be acceptable, sanctified by the Holy Spirit.
