“If ye abide in me, and my words abide in you, ye shall ask what ye will, and it shall be done unto you.”
John 15:7
Here is how you get whatever you desire to be done for you, even if you were the first one it would be specially fabricated for! Jesus said if you remain in him and his words remains in you; you would have whatever YOU will. Just WILL it and it shall be done! What a strong assurance!
The word of God must remain in you because when what you will is being done for you, at times, some good amount of time might have to be expended just like it happened with Jesus:
“And Jesus answered and said unto it, No man eat fruit of thee hereafter for ever. And his disciples heard it… And in the morning, as they passed by, they saw the fig tree dried up from the roots.” Mark 11:14, 20
But if you don’t doubt in your heart but believe and vocalize what you believe just like Jesus, you’d have the desires of your heart:
“For verily I say unto you, That whosoever shall say unto this mountain, Be thou removed, and be thou cast into the sea; and shall not doubt in his heart, but shall believe that those things which he saith shall come to pass; he shall have whatsoever he saith.” Mark 11:23
God wants to give you your desires and he starts by renewing your mind with his word and ensuring his word that has now become your desire is manifest in your life.
