The Meaning of Sonship

Watchman Nee tells about a new convert who came in deep distress to see him. 

"No matter how much I pray, no matter how hard I try, I simply cannot seem faithful to my Lord. I think I'm losing my salvation." 

Nee said, "Do you see this dog here? He is my dog. He is house-trained; he never makes a mess; he is obedient and a pure delight to me. 

Out in the kitchen, I have a son, a baby son. He makes a mess, throws his food around, fouls his clothes, and is a total mess. 

But who is going to inherit my kingdom? Not my dog; my son is my heir. 

You are Jesus Christ's heir because it is for you that He died." 

We are Christ's heirs, not through our perfection but by means of His grace.
