This book was inspired by our crucial need to be prepared for Christ's soon coming as we experience the assurance of salvation in our Savior.
However, many good Christians do not feel that they are good enough to be saved, no matter how hard they try. But no one is good enough except Jesus. For in His perfect goodness He died to exchange our sin for His righteousness, and our death for His life--abundant and eternal.
The only hopeful way to experience personal assurance is to trust Jesus to do our human best, combining it with His divine best--becoming complete in Him.
As we heartedly do our best, He steps into our struggles, compensating for all our human deficiencies by His grace. Let us always remember that the greatest good work we can do, as we walk with Jesus, is to keep on coming to Him, regardless.
