Friend or not?

Recently, my heart hurt for my son. Social skills are difficult for him. His preschool class this past year was 90% girls and only 5 boys. One of the other boys Samuel was a good friend to Jake, but the other boys weren't that close with him. They were by no means unkind, they just weren't as friendly. This past week we ran into one of these little boys around town. I encouraged Jacob to go say hi to him. Jacob went up and told the child where he knew him from and asked would he like to play with him. The boy, turned up his nose at Jacob and wouldnt answer him. I dont know if he was shy, didnt remember Jake or didnt want to play with him. All I know is that when I asked him later, Jacob said that he was sad that he couldnt play with his schoolmate.
I know that every child is exposed to this behavior, but I ache to know that it is probably because Jake has problem playing appropriately and being on the same level as other boys his age. He still likes playing with toys that his 3 year old brother likes and sometimes, I have to encourage him to pick more 'mature' toy choices.
I am encouraged by his growth socially over the last few months. He is doing so well, that many people dont even realize that he's delayed.
I keep reminding myself that the point of life is not to be well liked or get along with everyone- the point of life is to know and love your Creator and serve Him with all of the unique talents that He provides you. Jacob has the gift of laughter and charm. He is full of energy and liveliness. He likes everyone and doesnt look down on anyone. What a gift.
Because of his comprehension issues with language, Chris and I struggle with how to help him understand who God is and how they can have a relationship together. I must rest in the fact that God loves him more than I ever could and that He'll take care of that, and I just need to be faithful to him by loving Christ with all of me, and Jacob will see God's love in me. Trust. I trust that God is my friend and he wont turn up His nose at me or my son.
