Many live as if they expected to spend eternity on earth and never to leave this world. They set themselves the task of gathering the whole world into their possession in order to feel safe.
It is greatly to our encouragement that though we cannot see into heaven, though it is a realm we have not yet entered, even now we can store up goods in heaven, which will be kept for us until our arrival. Where better to put what we value most than in a place which is beyond the reach of all harm? A man who saves does so because he looks forward to some great future purchase, or to a day when the purchasing power of his money will be so much greater. We cannot take earthly currency to heaven, but God will ensure that when we arrive in heaven, we are rich beyond measure. Our treasure is first of all the Lord himself: he is our exceeding great reward. We have eternity to look forward to with him. We have the gold of a sanctified heart, the enjoyment of others who have come to Christ through our testimony, a store of knowledge of God’s truth, a record of having served him in the world.
How do we lay up treasure in heaven? We often face a choice between pleasing ourselves or pleasing the Lord. It is obvious to us that in choosing to please the Lord we forfeit some earthly advantage: the opportunity to boost our reputation before men, or to enrich ourselves, or hide some evil we have done, to hurt another we dislike, or to make friends with God’s enemies. We have the opportunity to witness to our boss but we hesitate to do so in case he thinks the worse of us and we lose promotion prospects. Do we give time to the study of Scripture, to go out and evangelise, to prepare a Sunday School lesson, when we are tempted to use our time for our own entertainment? We have already spent a sufficient amount of time on our own pleasure, but now we must give God a due portion of our time. The reward will be great, but we must discipline ourselves to start this.
How can we be said to receive a reward in heaven which we can never deserve? All the blessings of heaven and our eternal reward come to us by grace alone. They are purchased for us by our Saviour. When he suffered and died on Calvary’s cross he took the entire weight of punishment which we should have deserved and borne throughout eternity. At the same time, by his perfect life he earned the blessings and the rewards of heaven for us all. So what does he mean when he says, ‘Lay up for yourselves treasures in heaven’? God in his grace has given us a system of encouragement which we do not deserve. It is as if we could earn a reward in heaven by in this life obeying Christ, rejecting the world, denying our lusts, and by doing these things genuinely please him. This provides us with a motivation, but it is a motivation based on love and gratitude, not on any mercenary consideration. When the saints reach heaven, they will cast their crowns before God’s throne in recognition that they do not deserve any reward at all, and they will acknowledge that all has come from him. Nevertheless, he has given them crowns and a reward and both are real, and that will be a further cause of gratitude and worship. The saints anticipate all these wonderful things.
