2 Corinthians 10:4 KJV (For the weapons of our warfare are not carnal, but mighty through God to the pulling down of strong holds;)
In the name of Jesus we can enter into the presence of God and make our prayer and supplication directly to our Father in heaven. The bible has many examples where prayers were answered with remarkable results.
Prayer for Peter’s deliverance
Acts 12:5 KJV Peter therefore was kept in prison: but prayer was made without ceasing of the church unto God for him.
And God sent an angel to deliver Peter from the prison.
Judges 16:28 KJV And Samson called unto the Lord, and said, O Lord God, remember me, I pray thee, and strengthen me, I pray thee, only this once, O God, that I may be at once avenged of the Philistines for my two eyes.
Samson through super natural strength brought down the temple of Dagon upon himself and the Phillistines. And Samson killed more in his death than they which he killed in his life.
Isaiah 38 :1 - 3 KJV In those days was Hezekiah sick unto death. And Isaiah the prophet the son of Amoz came unto him, and said unto him, Thus saith the Lord, Set thine house in order: for thou shalt die, and not live.
2 Then Hezekiah turned his face toward the wall, and prayed unto the Lord,
3 And said, Remember now, O Lord, I beseech thee, how I have walked before thee in truth and with a perfect heart, and have done that which is good in thy sight. And Hezekiah wept sore.
God added fifteen years to his life.
These are just a few examples of how effective prayer can be. Let us not neglect this precious gift from God.
