"Do you believe in prayers?"

It's another great opportunity to take part in this contest. I want to thank @okere-blessing for this great contest tag (Do you believe in prayer)

source

Prayer is an act of communicating with
God. It expresses praise, thanksgiving, confession and request.

Yes. It is very necessary to pray because it brings us into a closer relationship with our creator, through his son, Jesus Christ. This relationship gives us the benefit of many blessings which GOD gives and which we need for day to day living. Such as:

1. Provision of our daily needs.
2. Granting of good health and strength to work.
3. Victory over all the problems of life.
4. Granting of the power of the holy spirit to help us grow in faith and perform works of miracles.
5. Divine blessings for prosperity in our homes, work and all that we lay our hands upon to do.
   One should pray always. The Bible In

1Thessalonians chapter 5 verse 17 admonished believers in Jesus Christ to Pray without ceasing (constantly, always, etc.).

Yes.

Yes and No.
Yes, I believe that some unanswered prayer is caused by sin because the bible in Isaiah 59:1-2 says that the prayer of a sinner is an abomination to God. Secondly James 4:3 also added that negative motives which is sin can hinder a person from receiving answers.

On the other hand, No, I don’t believe that unanswered prayer is caused by sin because Some evidences had shown that delay is not denial. At the appointed time it will come to pass. Maybe not GOD appointed time, maybe God wants to test your faith to know if it’s still strong and it may also be that God wants to manifest his power in that situation.
Looking at Hannah in the bible:
HANNAH: If because of her sin that she could not conceive that means it would have been forgiven because she had been praying before now. But when it was GOD’S appointed time for Samuel to come he came.

I would love to invite @sahar78, @bela90 and @adachukwu to take part in this contest.

THANKS.
