The Cross demonstrates that we do not gain by trying to get, but by losing in order to gain. We cannot really receive from God until we have learned to give up to God. It is the spirit which cries, “Not my will, but Yours be done” and “Father, into Your Hands I commit my spirit.”
These words are easily uttered, but we cannot appreciate them or really experience them until we have been through our Gethsemane experiences and our Golgotha experiences. Until that time we are merely reciting some words, but we do not truly know what it means to give ourselves up to God, to be completely consecrated and submitted to Him. The Cross prepares us to receive by first forcing us to give up. Therefore, the Cross is gaining through losing.
