Ephesians 6:18 & Jude 1:20 - Pray in the Spirit

We are to live or walk in the Spirit
Gal 5:16 (KJV)  This I say then, Walk in the Spirit, and ye
shall not fulfil the lust of the flesh.

We are to do all things by His Spirit:
Zec 4:6b (KJV) Not by might, nor by power, but by my spirit,
saith the LORD of hosts.

So why shouldn't we pray in the Spirit:

Well just how do we pray in the Spirit:

It is praying while guided by the Spirit of God: [Ryrie SB]

It is praying as the Spirit leads.  [Wiersbe Expository Outlines]

It is to pray in the power and strength of the Holy Spirit.
[Life Application SB]

It is to pray according to the Spirit's promptings and with the
power of the Spirit.[NIV SB]

It is to pray in accordance with the Holy Spirit's directives
and with the Spirit's aid. SDA Com

It is to pray under his guidance and influence, according to the
rule of his word, with faith, fervency, and earnestness; this is
praying in the Holy Ghost. [Matthew Henry Commentary]

It is to submit our hearts and minds to the direction and
leading of the Holy Spirit and then pray in his power. [Quest SB]

It is holding fast the divine influence which ye have received,
and under that influence making prayer and supplication to God.
(Adam Clarke Commentary)

Mark the grand characteristic of true prayer-"In the Holy
Ghost." The seed of acceptable devotion must come from heaven's
storehouse. Only the prayer which comes from God can go to God. We must
shoot the Lord's arrows back to him. That desire which he writes upon
our heart will move his heart and bring down a blessing, but the
desires of the flesh have no power with him.
Praying in the Holy Ghost is praying in fervency. Cold prayers
ask the Lord not to hear them. Those who do not plead with fervency,
plead not at all. As well speak of lukewarm fire as of lukewarm
prayer-it is essential that it be red hot.
It is praying perseveringly. The true suppliant gathers force as
he proceeds, and grows more fervent when God delays to answer. The
longer the gate is closed, the more vehemently does he use the knocker,
and the longer the angel lingers the more resolved is he that he
will never let him go without the blessing. Beautiful in God's sight
is tearful, agonizing, unconquerable importunity.
It means praying humbly, for the Holy Spirit never puffs us up
with pride. It is his office to convince of sin, and so to bow us
down in contrition and brokenness of spirit. We shall never sing
Gloria in excelsis except we pray to God De profundis: out of the
depths must we cry, or we shall never behold glory in the highest.
It is loving prayer. Prayer should be perfumed with love,
saturated with love-love to our fellow saints, and love to Christ.
Moreover, it must be a prayer full of faith. A man prevails only
as he believes. The Holy Spirit is the author of faith, and
strengthens it, so that we pray believing God's promise. O that this blessed
combination of excellent graces, priceless and sweet as the spices of the
merchant, might be fragrant within us because the Holy Ghost is in our
hearts! Most blessed Comforter, exert thy mighty power within us,
helping our infirmities in prayer., Morning and Evening by Charles H.
Spurgeon

It seems that to pray in the Spirit would require some listening
time.

Is He already trying to impress you with an answer to your
prayers?

Is He asking you to do something?

Prov 3:6 (KJV)  In all thy ways acknowledge him, and he shall
direct thy paths.
