Ephesians 1:13-14

So it is with you. You heard the true teaching—the Good News about your salvation. When you heard it, you believed in Christ. And in Christ, God put his special mark on you by giving you the Holy Spirit that he had promised. That Holy Spirit is the guarantee that we will get what God promised for his people. This will bring full freedom to the people who belong to God, to bring praise to God’s glory.
