From my devotional reading today which touched me . Max Lucado's book, In the Eye of the Storm.

A day is coming when everyone will hear Jesus' voice. A day is coming when all the other voices will be silenced; His voice--and His voice only will be heard.

Some will hear His voice for the very first time. It's not that He never spoke, it's just that they never listened. For these, God's voice will be the voice of a stranger. They will hear it once--and never hear it again. They will spend eternity fending off the voices they followed on earth.

But others will be called from their graves by a familiar voice. For they are sheep who know their shepherd. They are servants who opened the door when Jesus knocked.

Now the door will open again. Only this time, it won't be Jesus who walks into our house; it will be we, who walks into His.

The greatest gift we can leave our children and a peaceful assurance for us before we leave them here on earth is the knowledge that they know Jesus, not from an intellectual viewpoint but from a relational  day to day dependence on Him and living for Him. This assures us and them that in the after-life we will see each other again. No amount of gold or silver can buy that.
