How long can we live in health?
Psalms 90:10 As for the days of your life, they contain seventy years or if due to strength, eighty years.

Psalms 91:16 With a long life I will satisfy thee.

Our covenant for healing.
Isaiah 53:4 Surely our griefs (sicknesses) He Himself bore, and our sorrows (pain) He carried, yet we ourselves esteemed Him stricken, smitten of God and afflicted.

Jesus delivers our healing.
Matthew 8:17 In order that what was spoken through Isaiah the Prophet might be fulfilled, saying, "He Himself took our infirmities, and carried away our diseases."

1 Peter 2:24 He Himself bore our sins in His body on the cross, that we might die to sin, and live unto righteousness; for by His stripes you were healed.

Our authority, His power.
Luke 10: 19 Behold, I have given you authority to tread upon serpents and scorpions, and over all the power of the enemy; and nothing shall injure you.

Romans 8:11 But if the Spirit of Him who raised Jesus from the dead dwells in you, He who raised Christ Jesus from the dead will also give life to your mortal bodies through His Spirit who indwells you.

Mark 16:17-18 And these signs will follow those who believe: In My name they will cast out demons; they will speak with new tongues, they will take up serpents; and if they drink anything deadly, it will by no means hurt them; they will lay hands on the sick and they will recover.

Our faith for healing.
Hebrews 11:6 But without faith it is impossible to please Him, for he who comes to God must believe that He is, and that He is a rewarder of those who diligently seek Him.

Hebrews 11:1 Now faith is the assurance of things hoped for, the evidence of things not yet seen.

James 5:15 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.

Our confidence for healing.
Mark 11:24 Therefore, I say to you: "All things for which you pray and ask, believe that you have received them, and they shall be granted you."

John 14:13-14 And whatever you ask in My name, that will I do, that the Father may be glorified in the Son. If you ask me anything in My name, I will do it."

Remember: Healing is a sign to the unbeliever! Hebrews 2:4
