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.
For further reflection...
"The Lord direct your hearts into the love of God, and into the patient waiting for Christ." - 2 Thessalonians 3: 5 (KJV)
