According to 1 Peter 1, our futures are secure. We have an inheritance to end all inheritances. It’s in heaven, reserved for each one of us, and nobody can rob us of it. Not only that, but God guarantees our safe arrival so we can receive it. He preserves us by his power while we live out our lives here one earth. So knowing we are heirs to his kingdom, how do we live? You would think Peter would tell us to get out there and become missionaries, or get busy feeding the poor, or dedicate ourselves to endless hours of prayer or serving the church. He does none of that. Instead he says we are to intentionally live holy lives that reflect the character of God. How do we do that? It means a renewed mind in God’s Word, and a knowledge of Christ and his gospel, and an understanding of our justification and sanctification in Christ. It’s believing and rejoicing in the answer to question 60 from the Heidelberg Catechism (see below). Armed with those truths, we can refuse to conform to the culture of the day, we can struggle against sin and unbelief, and we can rouse ourselves in the Holy Spirit to be conscientious about our lives as Christians.
