What you are saying, about God's answers to be "Yes, No, and Not Right Now" is
False, and untrue.
And what do you mean when you say: Be
realistic? Are we walking after the flesh?
Do you advice a believer to STOP begging God? What?
If what you are saying was true, how would you be able to know and trust GOD to answer your prayers?
How can you have faith, if His answers are Yes, No, and Not right now - and you don't know?
It's not possible.
Hebrews 11:6 King James Version (KJV)
6 But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him.
James 1:5-8 King James Version (KJV)
5 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.
Matthew 21:21-22 King James Version (KJV)
21 Jesus answered and said unto them, Verily I say unto you, If ye have faith, and doubt not, ye shall not only do this which is done to the fig tree, but also if ye shall say unto this mountain, Be thou removed, and be thou cast into the sea; it shall be done.
22 And all things, whatsoever ye shall ask in prayer, believing, ye shall receive.
Mark 11:23 King James Version (KJV)
23 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.
To enlighten you further, I would ask you to read
from 2 Corinthians 1:15 ....
15 And in this confidence I was minded to come unto you before, that ye might have a second benefit;
16 And to pass by you into Macedonia, and to come again out of Macedonia unto you, and of you to be brought on my way toward Judaea.
17 When I therefore was thus minded, did I use lightness? or the things that I purpose, do I
purpose according to the flesh, that with me there should be
yea yea, and
nay nay?
18 But
as God is true, our word toward you was
not yea and
nay.
19 For the Son of God, Jesus Christ, who was preached among you by us,
even by me and Silvanus and Timotheus, was
not yea and
nay,
but in him was yea.
20 For
all the promises of God in him are yea, and in him
Amen, unto the
glory of God by us.
21 Now he which stablisheth us with you in Christ, and hath anointed us,
is God;
22 Who hath also sealed us, and given the earnest of the Spirit in our hearts." ....
Luke 18:7-9 King James Version (KJV)
7 And shall not God avenge his own elect, which cry day and night unto him, though he bear long with them?
8 I tell you that he will avenge them speedily.
Nevertheless when the Son of man cometh, shall he find faith on the earth?
