1 PETER 4:7 (NIV) 

The end of all things is near. Therefore be alert and of sober mind so that you may pray.

The highest calling of every Christian is to pray, converse, with his/her Heavenly Father about the business of the day or the hour. 

Here, in obedience to His will, we can co-operate & co-labor with heaven to realize "THY WILL BE DONE, ON EARTH AS IN HEAVEN!"
