1. Time – whether praying, or sending or going – all three take time
2. Treasure = money – those that stay home and support missions, it cost them in sacrificial and regular giving, but true believers want to worship the Lord through giving and want to grow in their giving to spread the kingdom of God. (see 2 Corinthians chapters 8-9)
3. For those who go – it can take a toll on health; there is suffering; there is the cost of being mis-understood by our own culture and thought “weird” (missionaries are different, let’s face it); and it costs the toll it takes on our children and them growing up in different cultures, etc. and family and for some, God calls them to martrydom – like John Wycliff in getting the Bible into English in the late 1300s and Jim Elliot and Raymond Lull, who were stoned by Muslims in North Africa in the middle ages.
It could cost you your life – Luke 9:23; Luke 14:26-33
Read and meditate on this on what Jesus said about discipleship and following Him – and this is not to be a missionary – this is to just be a follower of Jesus – a disciple! The big issue is not “missions”, but if more church goers were true disciples, more disciples would be going to the mission field and supporting missions, because they would be surrendered to whatever the Lord wants in their life.
Discipleship means that all other relationships are secondary to Jesus
26 “If anyone comes to Me, and does not hate his own father and mother and wife and children and brothers and sisters, yes, and even his own life, he cannot be My disciple.
Discipleship means I surrender my own rights to run my own life:
27 Whoever does not carry his own cross and come after Me cannot be My disciple.
28 For which one of you, when he wants to build a tower, does not first sit down and calculate the cost to see if he has enough to complete it? 29 Otherwise, when he has laid a foundation and is not able to finish, all who observe it begin to ridicule him, 30 saying, ‘This man began to build and was not able to finish.’ 31 Or what king, when he sets out to meet another king in battle, will not first sit down andconsider whether he is strong enough with ten thousand men to encounter the one coming against him with twenty thousand?32 Or else, while the other is still far away, he sends a delegation and asks for terms of peace.
Discipleship means surrendering up all our possessions to the Lordship of Jesus:
33 So then, none of you can be My disciple who does not give up all his own possessions.
4. But normally, the cost of sending a missionary couple or single or team to another culture will depend on the economy and situation of that specific culture and country. Right now, Japan and Western Europe are probably the most expensive places to live, but Africa and other parts of Asia and Latin America are less expensive, generally.
