2 Corinthians 1:22 AMP
22 it is He who has also put His seal on us [that is, He has appropriated us and certified us as His] and has given us the [Holy] Spirit in our hearts as a pledge [like a security deposit to guarantee the fulfillment of His promise of eternal life].
Who cannot love a God like that. He has taken us and sealed us to Him and made this pledge to us. He has given us promises that He very will intends to keep and make manifest in our lives if we are in Christ.
