Something happens all the time somewhere, at any time, including today. People expect that God will come and everything will immediately be fixed. But God says in His Word that He has already done everything required. Please understand that God is not going to do anything to save any people again, but now God wants to find those through whom He can convey the message that He has already done it. That is what God wants from the church. He said "I will build a church and entrust the Church the most important message that I have for this world". God wants the church to be able to tell people who are lost the message which He entrusted it with. This is why it is important that the church should never forget for what it was created.
Only the church has the most important message, which is able to change people's lives and bring them into eternity .
The responsibility of the church today is to bring the Word of God, to carry the message. Responsibility of God is to confirm that the message is true. Matthew 28:19-20
