Yep, exactly. When He gives us the desire of our heart then we are going to desire only what He desires. He also said that He would write His law on our heart so that we would fulfill it in all righteousness.

Psa 37:4-5 Delight thyself also in the LORD; and he shall give thee the desires of thine heart. (5) Commit thy way unto the LORD; trust also in him; and he shall bring it to pass.

When we enter His rest and delight ourselves IN HIM...in his holiness then we will desire what he desires. That is when we cease to be double minded and all of our prayers will be answered.

Jas 1:5-8 If any of you lack wisdom, let him ask of God, that giveth to all men liberally, and upbraideth not; and it shall be given him. (6) But let him ask in faith, nothing wavering. For he that wavereth is like a wave of the sea driven with the wind and tossed. (7) For let not that man think that he shall receive any thing of the Lord. (8) A double minded man is unstable in all his ways.

When we enter His rest He can be glorified in us.

2Th 1:10-12 When he shall come to be glorified in his saints, and to be admired in all them that believe (because our testimony among you was believed) in that day. (11) Wherefore also we pray always for you, that our God would count you worthy of this calling, and fulfill all the good pleasure of his goodness, and the work of faith with power: (12) That the name of our Lord Jesus Christ may be glorified in you, and ye in him, according to the grace of our God and the Lord Jesus Christ.
