"Be joyful in hope, patient in affliction, faithful in prayer." Romans 12:12

As we continue in the admonition of Romans 12:12 let's look at 'faithful in prayer.' That part of our verse is translated as:
"...faithful in prayer." The New International Version "...devoted to prayer." New American Standard Bible "...continuing steadfastly in prayer." New King James Version "...be constant in prayer." The Amplified Bible "...steadfastly maintain the habit of prayer." The New Testament in Modern English (J.B. Phillips)

"Strong's Exhaustive Concordance of the Bible" uses 'continuing' in referring to this portion of our verse. The Greek word is PROSKARTEREO which means: to be earnest toward, to persevere, be constantly diligent, to adhere closely, continue instant in.

There is a cross reference to Luke 18:1 (Read the parable Vs. 1-8), "Then He (Jesus) spoke a parable to them, that men always ought to pray and not lose heart."
And among others is Colossians 4:2,
"Continue earnestly in prayer, being vigilant in it with thanksgiving."

I quote the following from "Vine's Expository Dictionary":
"Faith is essential to prayer...for faith is the recognition of, and the committal of ourselves and our matters to, the faithfulness of God."

We are living in a time when there is a great need of prayer all around us.
As servants of the Most High God, let us make this admonition a priority and let the Holy Spirit guide us in the privilege of praying for God's will to be done on earth as it is in heaven.

Concerning prayer, Scripture tells us there is -- A need for purity of heart as the Psalmist tells us in Psalm 66: 18, "If I regard iniquity in my heart, The Lord will not hear."

A need to believe:
Jesus speaking in Matthew 21:22,
"And all things whatever you ask in prayer, believing, you will receive."

We ask in Jesus' name (again Jesus speaking):
"And whatever you ask in My name, that I will do, that the Father may be glorified in the Son." John 14:13

We ask according to God's will:
"Now this is the confidence that we have in Him (God), that if we ask any thing according to His will, He hears us." 1 John 5:14

The Holy Spirit aids us:
"And in the same way the Spirit also helps our weakness; for we don't know how to pray as we should, but the Spirit Himself intercedes for us with groanings too deep for words; and He who searches the hearts knows what the mind of the Spirit is, because He intercedes for the saints according to the will of God." Romans 8:26-27

As for posture, Scripture speaks of several--
Standing:
"...Stand up and bless the Lord your God forever and ever!."
Nehemiah 9:5 (Read Vs. 1-3 for background.)

Kneeling:
"At the evening sacrifice I rose from my fasting; and having torn my garment and my robe, I fell on my knees and spread out my hands to the Lord my God."  Ezra 9:5

Sitting:
1 Chronicles 17:16-27 is David's prayer of praise. Vs. 1 says, "Then King David went in and sat before the Lord..."

Bowing:
"So Moses made haste and bowed is head toward the earth, and worshiped.
Then he said 'if now I have found grace in Your sight, O Lord, let my Lord, I pray, go among us...'" Exodus 34:8-9

Hands lifted (here the Apostle Paul is writing Timothy concerning public
worship):
"Therefore I desire that the men pray everywhere, lifting up holy hands, without wrath and doubting." 1 Timothy 2:8

There is so much more concerning prayer, but I leave it to each of us to do a personal study for the prayers of Believers are so important at this time.

Thank You Lord for this great privilege of coming to You in prayer for the many needs of the people. Amen
