God's plan and commission cannot be altered by humankind's delay. This is not a time to sleep in passivity and convenience, but a time to build God's Kingdom. This book is about the challenge and the call of awakening addressed to the remnants who returned from captivity to engage God's enterprise and build for Him. Despite the economic troubles and opposing events that they faced, God encouraged them to wake up and pursue the divine destiny He had for them to be co-workers in His Kingdom. The same challenge is also applied to us in this shaking world. The book reveals that God's plan and commission can never be altered by the delay in the human kingdom. If there has ever been a time to engage God's work, now is the time. This is not a time to sleep in passivity and convenience, but a time to build for Him. The reader will be challenged; church leaders will challenged to approach ministry, not as actors, but as those who equip the rest for the work of ministry; and believers will discover their uniqueness in Christ and become effective in serving God.
