Jesus shows us the way to God and how to live. He said, “...I am the way, the truth, and the life. No one comes to the Father except through Me.” – John 14:6 NKJV    “…He who abides in Me, and I in him, bears much fruit; for without Me you can do nothing.” – John 15:5 NKJV   Finally, "For there is one God and one Mediator between God and men, the Man Christ Jesus,” – 1 Timothy 2:5 NKJV

Thus, we have our relationship with God through Jesus. Christians are to follow Jesus's example. "Jesus answered,…"'f anyone loves Me, he will keep My word; and My Father will love him, and We will come to him and make Our home with him.'" – John 14:23 NKJV

Is Jesus healing believers and performing other miracles today?

No.  Miracles in the early church were for the purpose of establishing that the Gospel was true. No man could do these things. The healing, speaking in tongues, and prophesying proved that the truths Jesus and the Apostles taught were from God. Once the church was established in God’s word, through the New Testament, these miracles ceased. When the Apostles and those upon whom the Apostles conferred these gifts died, the miraculous gifts ended.

Today, we have the whole New Testament and the Bible. The truths in the Bible transform us into Christ's image. Jesus taught His disciples when he prayed, “Sanctify them by Your truth. Your word is truth.” – John 17:17 NKJV    “All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness,  that the man of God may be complete, thoroughly equipped for every good work.” – 2 Timothy 3:16-17 NKJV

Were consecrated Christians ever healed in the early church?

No. Healing and speaking in tongues were not for believers. They were a witness to unbelievers to believe the Gospel. The Apostle Paul healed unbelievers, but could not use his gift to heal his own eyesight. He also wrote to Timothy saying, “Stop drinking only water, and use a little wine because of your stomach and your frequent illnesses.” – 1 Timothy 5:23 NIV  

Consecrated believers are to accept their trials as permitted of the Lord. The trials teach us to trust God and to develop our characters.   “… ‘My grace is sufficient for you, for my power is made perfect in weakness.’ Therefore I will boast all the more gladly about my weaknesses, so that Christ's power may rest on me. That is why, for Christ's sake, I delight in weaknesses, in insults, in hardships, in persecutions, in difficulties. For when I am weak, then I am strong.” – 2 Corinthians 12:9-10 NIV
