Pray Often
Pray without ceasing.
I Thessalonians 5:17

But we will give ourselves continually to prayer, and to the ministry of the word.
Acts 6:4

Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you.
Matthew 7:7

Evening, and morning, and at noon, will I pray, and cry aloud: and he shall hear my voice.
Psalm 55:17

Pray Soberly
But the end of all things is at hand: be ye therefore sober, and watch unto prayer.
1 Peter 4:7

Pray with Humility
And when thou prayest, thou shalt not be as the hypocrites [are]: for they love to pray standing in the synagogues and in the corners of the streets, that they may be seen of men. Verily I say unto you, They have their reward. But thou, when thou prayest, enter into thy closet, and when thou hast shut thy door, pray to thy Father which is in secret; and thy Father which seeth in secret shall reward thee openly. But when ye pray, use not vain repetitions, as the heathen [do]: for they think that they shall be heard for their much speaking. Be not ye therefore like unto them: for your Father knoweth what things ye have need of, before ye ask him.

After this manner therefore pray ye: Our Father which art in heaven, Hallowed be thy name. Thy kingdom come. Thy will be done in earth, as [it is] in heaven. Give us this day our daily bread. And forgive us our debts, as we forgive our debtors. And lead us not into temptation, but deliver us from evil: For thine is the kingdom, and the power, and the glory, for ever. Amen.
Matthew 6:5-13

Pray With Thanksgiving
Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God.
Philippians 4:6

Pray With Joy
Always in every prayer of mine for you all making request with joy,
Philippians 1:3-4

Pray in and with the (Holy) Spirit
I will pray with the spirit, and I will pray with the understanding also: I will sing with the spirit, and I will sing with the understanding also.
1 Corinthians 14:15

Likewise the (Holy) Spirit also helpeth our infirmities: for we know not what we should pray for as we ought: but the Spirit itself maketh intercession for us with groanings which cannot be uttered. And he that searcheth the hearts knoweth what [is] the mind of the Spirit, because he maketh intercession for the saints according to [the will of] God.
Romans 8:26-27
