In Him, you also, after listening to the message of truth, the gospel of your salvation — having also believed, you were sealed in Him with the Holy Spirit of promise, who is given as a pledge of our inheritance, with a view to the redemption of God's own possession, to the praise of His glory.
The Holy Spirit was given to you at the time of your salvation as proof from God that you were in Christ and would receive the full experience of glory at the end!
Look at what happens in this verse. First, you heard the gospel of your salvation. At that time you believed; you trusted in Christ's death on the cross for the forgiveness of your sins. When you believed, you were united with Christ and the thing that sealed you in that relationship was the Holy Spirit, who God gave you at that time as a pledge of your eternal inheritance. The word translated "pledge" means "down payment" or "deposit". It is the first part of a much larger payment that is to come.
Today God is promising you that the work of redemption He is doing in your life right now, making you more and more like Jesus, will one day be complete. You are God's precious possession. God will not abandon you. You have been sealed in Christ and God the Father will never abandon Jesus Christ His Son.
