But there is even more to it than that, because now the illustration is broadened. It is not only a seal, but it is ‘the earnest’.
Do you know peace even now in your earthly walk? Not all the time, but you know the experience of God’s peace. And then when you get to heaven, there will be unlimited and amazing unrestrained joy and happiness. Isn’t your heart often filled with happiness even among all the distresses of this present life? A degree of happiness you never knew before you were a Christian, joy and happiness, not only peace in believing. It is a token; it is a pledge; it is a down payment. And then your understanding: in heaven we shall mingle with the inspired writers of the word, and we often amuse ourselves with the thought that we shall ask perhaps this one or that one, ‘What did you mean by this? What did you mean by that?’ But our minds will be filled with understanding and realisation of so much. And then fruits, you will see in heaven the fruits of all your labours, the people who are there, and you will learn for the first time perhaps, that it was through your witness or your prayers, that this one or that one was brought to salvation. Then you will lose all pain and all fear and anxiety and grief as part of rest and peace. Sometimes you have that experience on earth when you are wonderfully delivered from some particular trial. We are secure on earth in Christ, but in heaven we will no longer question it. In heaven love for God will be perfect and refined and absolute, and even now there are times when we really do feel an intense love for the Lord here on earth. All these are part of the sealing of the Spirit. It is a seal on the one hand, it is a down payment or token of heavenly glory on the other. Have you not had the tokens? Of course you have. Have you not had the earnest, the foretaste, the down payment? How assuring that is! It gives us perspective in trial, it increases our anticipation, it helps us in self-denial when we know to have this and that which is too expensive is wrong. It increases our thanksgiving. It strengthens our service.
