Aligning priorities...

We can really seek God's Kingdom only when we love the Lord more than anybody or anything else in this world. Only when we passionately love Him will we be serious to do God's work. That is why when Peter told Jesus that they had left everything to follow Him did Jesus say,

Luke 18:29-30 [NASB]
And He said to them, 'Truly I say to you, there is no one who has left house or wife or brothers or parents or children, for the sake of the kingdom of God, Who will not receive many times as much at this time and in the age to come eternal life'

This scripture does not indicate literally leaving behind our families, but our place for God in our hearts should be above everyone and everything else. To love Him is to seek to please Him and do His will all the time...Only when we are willing to love Him above all, will we be able to work for His kingdom effectively.
