What we see now as a disappointment we may later understand as a heavenly redirection. God is getting you in a position to receive blessings you might not even know to ask for. Paul and Silas set out for Asia, but ended up being the first to bring the gospel to Europe! (Acts 16:7) God had something even greater in store than what they originally had in mind.
Rejection is nothing more than redirection. God will use all things to bring about the greater things He has in store – for His glory, and your good!
