That the earth and the heavens will be “folded up” reveals that the earth is not permanent or indestructible. God placed Jesus in authority over all of creation, so we dare not treat any created object or earthly resource as more important than he is.
When we spend more time on ourselves than on serving Christ, we treat ourselves (his creation) as being more important than our Creator. When we regard our finances, rather than our faith in Christ, as the basis for our security, we give higher status to an earthly resource than we do to our God. Rather than trusting in changeable and temporary resources, trust in God, who is eternal.
