Is it a blessing to live long on the earth? [Ephesians 6:2-3] "Honour thy father and mother; (which is the first commandment with promise;) That it may be well with thee, and thou mayest live long on the earth."


Are we supposed to desire to live long on the earth?  It seems to me that after someone in born again he/she is looking forward to meeting and serving and worshiping our Lord forever. 

All these can be done although with difficulties on this earth. I am not saying we should desire to not live and serve our Lord on this earth.

It is also not about us but about Him.
So is God more pleased in giving us more years, maybe because we get the chance to become more pure?
Philippians 1:21-24 (NASB)
  For to me, to live is Christ and to die is gain. But if I am to live on in the flesh, this will mean fruitful labor for me; and I do not know which to choose. But I am hard-pressed from both directions, having the desire to depart and be with Christ, for that is very much better;  yet to remain on in the flesh is more necessary for your sake.


Paul's desire was to go home to be with the Lord. He was, however, content to stay for the sake of serving others. Being blessed with a long life gives us more of an opportunity to glorify God, which is good for us, too.

Addendum: It is also possible for our desire to leave the troubles of this life behind to have selfish motivations. It is better (for us) to be with the Lord, but it is better for others that we remain here. What should an unselfish person choose?
