Singleness can strengthen our inward character and qualities. It is the time to gain the strength to stand alone and the time to discover His gentle arms of love. Singleness also allows time to focus on practical preparation - a time to discover and develop one's talents and life skills... and how to use it for the Lord.
Singleness is a time to seek God with an undivided and undistracted heart. Being single is an opportunity to discover who God has made us to be and what He has called us to in this life.
Singleness is the best time to bless others as much as possible :)
