"Over this past weekend we've started to see signs that his weakened breathing is causing vital organs to become oxygen deprived," reads a post on his website.
Jackson has been battling cancer since May 2014 after doctors found a large, aggressive growth in his leg that needed immediate treatment. Through this experience, he wrote how cancer taught him much about how seriously God takes our fears and vowed to use prayer to fight it.
"I am pursuing the Kingdom of God and equipping people to do the same as vigorously as I am able. I refuse to allow the enemy a stronghold in my thoughts. God is great and all-powerful," Jackson said in 2014. "I believe He will take me through this battle. In the process, God will gain a great victory and His name will be glorified."
Jackson is the founder of Streams Ministries International, a ministry that works to encourage, motivate and equip people to walk in greater maturity, wisdom, character and holiness. Jackson is perhaps best-known for his Biblical approach to dream interpretation and prophetic evangelism, Charisma previously reported.
According to his website, Jackson's Biblical approach to dreams revealed their life-changing purpose and restored an overlooked way God chooses to communicate with people. His "explanations of the unexplainable" helped people relate to God and each other in fresh ways.
Jackson launched Streams Ministries International in 1993. Their mission statement, according to the website, is to touch people with the message of God's love, bring the awe of God back into the church and transform lives through the supernatural of the Holy Spirit.
Please pray for the Jackson family.
