We miss those we love who have gone on to be with the Lord. We wonder what they would think, or if they would be pleased with us. We get hung up on trinkets and items that spark memories. We sometimes focus on our failures and second guess our actions. When we do these things we focus on the sadness of what they were instead of the glory of what God makes them.
Revelations 20:6 Blessed and holy is he that hath part in the first resurrection: on such the second death hath no power, but they shall be priests of God and of Christ, and shall reign with him a thousand years.
Farmers do not grieve the loss of the seed, they instead focus on the wonderful plant that grew from it. As Christians we should always remember that God will grow us into something mighty and glorious in his time.
