Here's another thought from Nancy Campbell that blessed me, especially now that we aren't going to Africa to be official missionaries.
Matthew 9:37-38, "Then said Jesus unto his disciples, The harvest truly is plenteous, but the laborers are few; pray ye therefore the Lord of the harvest, that he will send forth laborers into his harvest."
Do you sometimes hanker to be doing some great work for God? You feel as though you are wasting your life in your home. You would love to serve the Lord in some harvest field. Yes, it is true, the harvest is great and the laborers are few. But why are they few? Because mothers have not understood God's purpose.
Are you looking for an easy path in life in life or do you have a heart to serve God as a missionary? Dear mother, you are already a missionary. God has chosen your specific mission field for you. It is your home and family. You are employed by God to train laborers for His harvest field. You don't raise children and then send them to Bible College to prepare for service. You train them for God's service from the time they are little. They should be ready to labor in the harvest field when they come forth from your home.
Is a missionary's work easy? No, it takes sacrifice. Is motherhood easy? No, but it will be worthwhile. It takes everything you've got--all your resources of time, energy and strength--but you will influence nations. It takes sacrifice--many mothering days are exhausting and overwhelming--but you will receive the fruit of your labors and an eternal reward. It will take committed prayer and intercession, but your prayers will be answered. Remember, you are not on vacation; you are on the mission field!
Maybe God has only given you one laborer to prepare for Him--that is His plan for you. Maybe he has given you six, or even twelve! Wow, would twelve be too many? Jesus trained twelve disciples who impacted the world. Are you going to train laborers who "turn the world upside down"? (Acts 17:6) You are already in the midst of an important mission... so get to work!
