It is good to know the time. This is true in every day terms but also good in terms of the moral state of the world and it is definitely important in terms of our personal moral state. The bible says that 'it is time to seek the Lord'. The following quotation from the bible highlights the urgency of hearing God's voice before it is too late.
“In a favorable time I listened to you, and in a day of salvation I have helped you.” Behold, now is the favorable time; behold, now is the day of salvation.
