Ephesians 3:6 This mystery is that through the gospel the Gentiles are heirs together with Israel, members together of one body, and sharers together in the promise in Christ Jesus.
When God calls you to do something difficult, it is probably not because He wants to test you and find out how much you can take – despite how you feel!
God will only call you to do something He knows you can do – and He is not going to be picky about whom He calls you to work with!
Sometimes God calls us to work with the people we feel most uncomfortable with – but He knows you will be able to do it!
