3 JOHN 2
Jesus gave His life to deliver us from this present evil world, Galatians 1:4, and to give us abundant life, John 10:10.
John walked closely with Jesus and was inspired by the Holy Spirit and wrote that more than anything He wanted all Christians to be healthy and to prosperous even as our souls prosper. That is what Jesus died for.
Jesus said that if we see Him, we see the Father because He and the Father were in agreement about everything. So if God the Father loved us enough to sacrifice His Son to purchase us then He would do anything for our good. He doesn't enjoy or sympathize at our poverty and sickness.
God's Word is clear that our soul and life will prosper as we open our heart to His love and provisions; spirit, soul and body. Not believing this has caused many to see God only caring about eternal needs.
But our great salvation includes so much more! God's power is to be manifested here and now. We shouldn't live without the benefits Jesus died to give us. He is glorified when we prosper and be in health even as our souls prosper. It gives Him pleasure when we walk in His goodness.
