If you are sure that He is calling and you can be sure that He will also remove the barriers that would preclude your service, in His perfect timing. Rest in that.

God will not lead you where He will not provide for you.

When you love the Lord, you long to glorify Him and see the nations fall at His feet in worship. When you love your neighbor as yourself, you share the gospel with him and seek to meet his needs in every way you can, which includes seeing him fall at Jesus' feet in thanksgiving for salvation.

What we can say for sure is that, at the very least, God calls every Christian to live with a missionary heart.

God has called every Christian to international missions, but He does not want everyone to go. God calls some to be senders.

One-third of the planet's population, over two billion people, has never heard the gospel. And of that number, over 50,000 die daily, separated from God forever.

Some of us are senders and some are goers. Neither is more important than the other. Neither is possible without the other.
