TASTE THE BLISS OF LIFE

Everything in life is temporary...

Darkness of the night or brightness of the day.

Even sunrise is temporary... And so is sunset. If things are going bad ...

It won't last forever And remember
the everlasting joy that comes from the Lord
may be the flame in your heart ,that
will keep you warm in those cold nitez..
Everything just passes by...
But the Love of God remainz!!!

Have a beautiful day!
Much Love

Every morning leave your worries outside the gate because that's where they pick up the garbage.

Have a Smiley Day ahead.
