When the call of God came to the Prophet Isaiah, he was willing and ready to go as God's messenger and share the word that God commanded him to proclaim.

God's call has been heard all through the ages, and those who surrendered to that call have been, and are being used mightily to fulfill God's plan and purposes.

The last words of Jesus given to His disciples in the great commission, is a call to every believer to go into all the world, make disciples, baptize and teach those who believe.

Have a happy day, and if every believer will obey Jesus' call, and go forth as His ambassadors into their spheres of influence, the world will be reached in no time.
