The young man saith to him: All these I have kept from my youth, what is yet wanting to me? Jesus saith to him: If thou wilt be perfect, go sell what thou hast, and give to the poor, and thou shalt have treasure in heaven: and come follow me. And when the young man had heard this word, he went away sad: for he had great possessions. Then Jesus said to his disciples: Amen, I say to you, that a rich man shall hardly enter into the kingdom of heaven. And again I say to you: It is easier for a camel to pass through the eye of a needle, than for a rich man to enter into the kingdom of heaven. And when they had heard this, the disciples wondered very much, saying: Who then can be saved? And Jesus beholding, said to them: With men this is impossible: but with God all things are possible. (Matthew 19:20-26, D-R)

How can you give up what you have when you have it in comfort? The answer is for God to release you from it. Then, do not complain, for you never had the strength to give it up yourself. He wants to draw you to Himself.
