We know that the Christian life is filled with times of both exhaustion and complacency, but we also know that Jesus has secured for us an ultimate victory that cannot be taken away. Thus, our journey becomes a victorious one. This isn't just about positive thinking; it's recognizing that God is guarding both our inheritance (heaven and perfect communion with him) and our souls. We will persevere to the end not because we become more disciplined people, but because God has promised that he will complete the work he has started in us (Phil. 1:6). That should make a difference in the way we sojourn through this world.
