Singleness is one of the stages of life that everyone passes through. Like other stages of life, being single has both strengths and weaknesses. There are lots of opportunities available to singles only, many struggles and challenges are peculiar to them.
Strengths of singles: Quick decision making; easy movement and relocation; less distraction, singleness in motive/concentration etc.
Struggles/ Challenges: Lack of partner for companionship and encouragement; the enemy uses this as an avenue to launch barrages of attacks (in form of temptations, accusations, depression etc). Singleness may not be acceptable in some culture; this poses a hindrance to their ministries.
Pressure (to get married) by family members, friends, colleagues or even leaders. Advancing in age is also a threat. At times, the daughters of Moab (Num 25) and sons of Harmor (Gen 34) may also flaunt themselves to take advantage of them. Leadership may also put pressure on a task which may not be easy to accomplish as a single. Fear of the future, the unknown, etc.
– Thank God for all the single missionaries. Thank God for how far He has used them and still equipping them. Pray that God should help them to further take advantage and make good use of the strength and opportunities that are available only to singles, to run faster and reach farther. Pray that God should shield them from people that come into their lives with ulterior motives, (the temptation to sin, false accusation, criticism, etc). Use Psalm 68:6 and Ex 1:21 to pray that God would put them in houses/families of their own.
