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 Chronicles 7:14 KJV
As true today as when it was spoken.
God has estabished a covenant with His peope and will not break it. When those in covenant with Him practice the covenant conditions, they have His full support.
We can expect His delivering, saving, power to be manifest on our behalf.
And Jesus answering saith unto them, Have faith in God. For verily I say unto you, That whosoever shall say unto this mountain, Be thou removed, and be thou cast into the sea; and shall not doubt in his heart, but shall believe that those things which he saith shall come to pass; he shall have whatsoever he saith. Therefore I say unto you, What things soever ye desire, when ye pray, believe that ye receive them, and ye shall have them. Mark 11:22-24 KJV
