Regardless of the need you have, prayer is the key that opens the door to God, to His blessings, power, healing, and solutions to problems. Bro. Jeff lists several potentials that prayer provides.
Hebrews 13:18-19, 23 (KJV)
18 Pray for us: for we trust we have a good conscience, in all things willing to live honestly.
19 But I beseech you the rather to do this, that I may be restored to you the sooner.
23 Know ye that our brother Timothy is set at liberty; with whom, if he come shortly, I will see you.
13 And whatsoever ye shall ask in my name, that will I do, that the Father may be glorified in the Son.
14 If ye shall ask any thing in my name, I will do it.
16 Ye have not chosen me, but I have chosen you, and ordained you, that ye should go and bring forth fruit, and that your fruit should remain: that whatsoever ye shall ask of the Father in my name, he may give it you.
24 Therefore I say unto you, What things soever ye desire, when ye pray, believe that ye receive them, and ye shall have them.
25 And when ye stand praying, forgive, if ye have ought against any: that your Father also which is in heaven may forgive you your trespasses.
1 John 3:22-23
22 And whatsoever we ask, we receive of him, because we keep his commandments, and do those things that are pleasing in his sight.
23 And this is his commandment, That we should believe on the name of his Son Jesus Christ, and love one another, as he gave us commandment.
1 John 5:14-15
14 And this is the confidence that we have in him, that, if we ask any thing according to his will, he heareth us:
15 And if we know that he hear us, whatsoever we ask, we know that we have the petitions that we desired of him.
3 Call unto me, and I will answer thee, and show thee great and mighty things, which thou knowest not.
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.
7 Ask, and it shall be given you; seek, and ye shall find; knock, and it shall be opened unto you:
14 Is any sick among you? let him call for the elders of the church; and let them pray over him, anointing him with oil in the name of the Lord:
1 And the prayer of faith shall save the sick, and the Lord shall raise him up; and if he have committed sins, they shall be forgiven him.
1 Timothy 2:1-2
1 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.
6 In my distress I called upon the Lord, and cried unto my God: he heard my voice out of his temple, and my cry came before him, even into his ears.
17 The righteous cry, and the Lord heareth, and delivereth them out of all their troubles.
15 He shall call upon me, and I will answer him: I will be with him in trouble; I will deliver him, and honour him.
32 But call to remembrance the former days, in which, after ye were illuminated, ye endured a great fight of afflictions;
33 Partly, whilst ye were made a gazingstock both by reproaches and afflictions; and partly, whilst ye became companions of them that were so used.
34 For ye had compassion of me in my bonds, and took joyfully the spoiling of your goods, knowing in yourselves that ye have in heaven a better and an enduring substance.
17 Elias was a man subject to like passions as we are, and he prayed earnestly that it might not rain: and it rained not on the earth by the space of three years and six months.
2 Corinthians 1:8-11
8 For we would not, brethren, have you ignorant of our trouble which came to us in Asia, that we were pressed out of measure, above strength, insomuch that we despaired even of life:
9 But we had the sentence of death in ourselves, that we should not trust in ourselves, but in God which raiseth the dead:
10 Who delivered us from so great a death, and doth deliver: in whom we trust that he will yet deliver us;
11 Ye also helping together by prayer for us, that for the gift bestowed upon us by the means of many persons thanks may be given by many on our behalf.
6 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.
10 Finally, my brethren, be strong in the Lord, and in the power of his might.
11 Put on the whole armour of God, that ye may be able to stand against the wiles of the devil.
12 For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.
13 Wherefore take unto you the whole armour of God, that ye may be able to withstand in the evil day, and having done all, to stand.
14 Stand therefore, having your loins girt about with truth, and having on the breastplate of righteousness;
15 And your feet shod with the preparation of the gospel of peace;
16 Above all, taking the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked.
17 And take the helmet of salvation, and the sword of the Spirit, which is the word of God:
18 Praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance and supplication for all saints;
24 Hitherto have ye asked nothing in my name: ask, and ye shall receive, that your joy may be full.
