Isn't it wonderful to get mail?  In my younger years I was thrilled to get a letter in the mail!
Every year my grandma Jones would send me a Valentine!  Valentines were beautiful  pictures with lovely rhymes 40 years ago!  I saved many of them and what a treasure they are today!  While I love to look at them time and again it is really the loving words that my grandmother wrote that means so much to me! My grandmother is with the Lord and I look forward to seeing her again!  Such precious memories of her are brought to mind when I  hold those Valentines in my hand.  They are links to her  loving heart! 
Letters link hearts together!
I  treasure cards and letters even more as an adult! Today I received some special mail.  One was a handmade thank you card. The front says "God works wonders through wonderful people!" The dear words inside expressed the gratitude of their hearts for the blessing and encouragement my husband and I  had been for helping them through a most difficult time!  Why do I share  these personal experiences?  So we will not forget to love others!  We do not always know  why the Lord lays a person  upon our heart or brings them to mind, but we must certainly realize God wants to bless their life  in a special way through us!
The beautiful results is that we are blessed too!
