God's seal

“... set His seal of ownership on us, and put His Spirit in our hearts as a deposit, guaranteeing what is to come.” 2 Corinthians 1:22
In his study on 2 Cor. 1, pastor Alwyn Wall tells how cargo being shipped in the Roman empire would bear a seal, imprinted with the signet ring of its owner. The seal indicates ownership, and would guarantee that the cargo would reach the final destination.
Likewise, we have been imprinted with God’s seal of ownership. What is this seal? Eph. 1:13 tells us it is the Holy Spirit. So the Holy Spirit is the seal upon us, and He is also the deposit placed inside our hearts. Both aspects guarantee what is to come.
A person buying goods gives a deposit as a downpayment. It means they are committed to receiving the goods, perhaps at a later date, and promise to pay the balance required. How amazing to think, God has done the same with us! He has paid the deposit, which means He is committed to receiving us (Phil. 1:6). God won’t change His mind about you. He has promised that you will reach the final destination.
