When we are feeling weak spiritually, we can pray and the Lord will strengthen us (2 Cor. 12:9). Here is an overview of why and how we should pray, as presented in the Bible:
“If my people, which are called by my name, shall humble themselves, and pray, and seek my face, and turn from their wicked ways; then will I hear from heaven, and will forgive their sin, and will heal their land” (2 Chron. 7:14).
“The righteous cry, and the Lord heareth, and delivereth them out of all their troubles. 18 The Lord is nigh unto them that are of a broken heart; and saveth such as be of a contrite spirit” (Psalm 34:17-18).
“Offer unto God thanksgiving; and pay thy vows unto the most High: 15 And call upon me in the day of trouble: I will deliver thee, and thou shalt glorify me” (Psalm 50:14-15).
“He will regard the prayer of the destitute, and not despise their prayer” (Psalm 102:17).
“The Lord is nigh unto all them that call upon him, to all that call upon him in truth. 19 He will fulfil the desire of them that fear him: he also will hear their cry, and will save them” (Psalm 145:18-19).
“The Lord is far from the wicked: but he heareth the prayer of the righteous” (Prov. 15:29).
“And it shall come to pass, that before they call, I will answer; and while they are yet speaking, I will hear” (Isaiah 65:24).
“For I know the thoughts that I think toward you, saith the Lord, thoughts of peace, and not of evil, to give you an expected end. 12 Then shall ye call upon me, and ye shall go and pray unto me, and I will hearken unto you. 13 And ye shall seek me, and find me, when ye shall search for me with all your heart” (Jer. 29:11-13).
“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. 7 But when ye pray, use not vain repetitions, as the heathen do: for they think that they shall be heard for their much speaking. 8 Be not ye therefore like unto them: for your Father knoweth what things ye have need of, before ye ask him. 9 After this manner therefore pray ye: Our Father which art in heaven, Hallowed be thy name. 10 Thy kingdom come. Thy will be done in earth, as it is in heaven. 11 Give us this day our daily bread. 12 And forgive us our debts, as we forgive our debtors. 13 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” (Matt. 6:6-13).
“Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you: 8 For every one that asketh receiveth; and he that seeketh findeth; and to him that knocketh it shall be opened” (Matt. 7:7-8).
“And all things, whatsoever ye shall ask in prayer, believing, ye shall receive” (Matt. 21:22).
“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).
“And in that day ye shall ask me nothing. Verily, verily, I say unto you, Whatsoever ye shall ask the Father in my name, he will give it you. 24 Hitherto have ye asked nothing in my name: ask, and ye shall receive, that your joy may be full” (John 16:23-24).
“Likewise the 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. 27 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).
“Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God. 7 And the peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus” (Phil. 4:6-7).
“I exhort therefore, that, first of all, supplications, prayers, intercessions, and giving of thanks, be made for all men; 2 For kings, and for all that are in authority; that we may lead a quiet and peaceable life in all godliness and honesty” (1 Tim. 2:1-2).
