Jesus is perfect theology. If you want a flawless depiction of what God is like, look at Jesus — at how He acted, how He preached, how He ministered to people and most importantly, how He loved them. Jesus shows us what the Father is like. For instance, in John 9, when He heals the blind man and His disciples ask Him, “Rabbi, who sinned, this man or his parents, that he should be born blind?” Jesus says, “Neither. He was born blind so that the glory of God could be revealed in His life.” And so it was, when Jesus healed him.
Jesus does not go around making people sick to teach them a lesson or harming them to get His point across; that is bad theology. Our loving Savior ministers through healing, loving, guiding and encouraging. He speaks truth to empower, however, He never intentionally hurts the people receiving His message. Circumstances may disappoint and there may be consequences that come as a result of decisions, but everything He does is for the benefit of those He calls His own.
Friend, you can trust Jesus to take care of you because He is good. He is the fullness of God and He acts in accordance with the heart of His loving Father. No matter what you go through or how bad it gets, He is with you and for you. Trust His heart, rest in His arms, and take comfort in His unfailing love.
