(a) Reasons why believers should prepare for the second coming are: that Christ would return suddenly (like a thief in the night). Therefore, believers should be prepared at all times. As children of the day / light, believers should be on guard and not asleep as others. Since believers live in the light / sins of the day, they should be sober and awake. Believers should put on their breastplate of faith and love, they should increase their faith in the Lord as they wait for the Second Coming of Christ. The hope of salvation should motivate every Christian to prepare for the Lord's coming. This is because the Lord has decided to save us through our Lord Jesus Christ and not to destroy us in His anger. Christ died for us so that whether we are awake or asleep, we might be with him in the hereafter / eternally. Christians are to encourage one another and to build one another up explaining why preparations should be made for the second coming.

(b) Significance of the Second Coming;
(i) The second coming is a time when God will intervene directly and dramatically in world affairs.
(ii) The day of punishment for sinners and reward for faithful believers.
(iii) The day Christ will judge sinners and set up his eternal kingdom.
(iv) The day God will defeat all the forces of evil.
