Too often we think of the Cross of Christ as something we have to get through, yet we get through for the purpose of getting into it. The Cross represents only one thing for us, complete, entire, absolute identification with the Lord Jesus Christ, and there is nothing in which this identification is more real to us than in prayer.
"Your Father knows the things you have need of before you ask Him" (Matthew 6:8). Then why should we ask? The point of prayer is not to get answers from God, but to have perfect and complete oneness with Him. If we pray only because we want answers, we will become irritated and angry with God. We receive an answer each time we pray, but it does not always come in the manner we expect, and out spiritual irritation shows our refusal to identify ourselves truly with our Lord in prayer.
Have you reached such a level of intimacy with God that the only thing that can account for your prayer life is that it has become one with the prayer life of Jesus Christ? Has the Lord exchanged your life with His vital life? If so then " in that day" you will be so closely identified with Jesus that there will be no distinction.
When prayer seems to be unanswered beware of attempting to place the blame on some else. This is always a trap of Satan. When you seem to have no answer, there is always a reason, God uses these times to give you deep personal instruction, and it is not for anyone else but you.
