If we do not wait patiently in expectation for God's coming in glory, we start wandering around, going from one little sensation to another. Our lives get stuffed with newspaper items, television stories, and gossip. Then our minds lose the disciline of discerning between what leads us closer to God and what doesn't, and our hearts gradually lose their spiritual sensitivity.
Without waiting for the second coming of Christ, we will stagnate quickly and become tempted to indulge in whatever gives us a moment of pleasure. When Paul asks us to wake from sleep, he says: "Let us live decently, as in the light of day; with no orgies or drunkenness, no promiscuity or licentiousness, and no wrangling or jealousy. Let your armour be the Lord Jesus Christ, and stop worrying about how your disordered natural inclinations may be fulfilled" (Romans 13:13-14). When we have the Lord to look forward to, we can already experience him in the waiting.
