“You are my witnesses,” declares the Lord, and My servant whom I have chosen, that you may know and believe Me and understand that I am He. Before Me no god was formed, nor shall there be any after me. I, I am the Lord, and besides Me there is no savior. I declared and saved and proclaimed, when there was no strange god among you; and you are My witnesses,” declares the Lord, “and I am God. Also henceforth I am He; there is none who can deliver from My hand; I work, and who can turn it back?”
Isaiah 43:10-13
The term Trinity itself isn’t found in the Bible, but it is a term that stems directly from and synthesizes several teachings found all throughout the Bible. “Trinity” gives us a succinct way to describe a complex and magnificent truth: that our one God exists in three distinct persons. We worship God the Father, God the Son, and God the Holy Spirit.
In today’s passage, God makes it clear that He is the one true God. Interestingly, in the middle of this passage, He also declares, “besides me there is no savior.” As we know, Savior is an often used title of Jesus throughout the New Testament. Here are just a few examples:
“For unto you is born this day in the city of David a Savior, who is Christ the Lord.” -Luke 2:11
“Of this man's offspring God has brought to Israel a Savior, Jesus, as He promised.” -Acts 13:23
“We have seen and testify that the Father has sent the Son to be the Savior of the world” -1 John 4:14
The text in Isaiah makes clear that there is no savior besides God. But we also see Jesus clearly identified as the Savior all throughout the gospels and epistles, with John even calling Him THE Savior of the world! Pairing these New Testament verses with Isaiah 43 points us toward the doctrine of the Trinity. This week, we’ll be studying through several other Bible passages that contribute to our understanding of this core belief.
Recently, on a flight to Japan, my husband was writing out his testimony to share with his Life Group there in Okinawa. His seatmate asked what he was working on, and Karl’s answer piqued his interest. This 21-year-old Japanese student had never heard anything about Jesus before, but he asked Karl to tell him more. Because the student was still learning English, Karl had to use simple vocabulary. And, since they both had plenty of time to spare during the ten-hour flight across the Pacific, Karl was able to tell the story of God and His people starting at the very beginning.
Karl said sharing these life-altering truths in such plain language with someone who had never heard them before reminded him of teaching our children about God. It got me thinking how passing my knowledge of God onto my kids has been so challenging to my own faith. Discipling toddlers has allowed me to approach the Bible with fresh eyes and has also continually provided me with fresh questions I need to answer.
Sometimes these questions come from my kids, but oftentimes, verbally explaining what I believe creates lots of questions in my own mind. I’ve often found myself telling a Bible story or explaining a core doctrine, like the Trinity, and thinking, “Why did it have to happen that way?” or, “Wait, how does that actually work?” and even, “Do I really believe this?”
At first these questions were unsettling, but I’ve come to embrace and appreciate them! They’ve driven me into deeper study and deeper prayer. None of my questions have ever intimidated God. My confusion and even my doubts don’t threaten Him. And He has been so faithful to continue to reveal His truth to me as I have sought Him. My confidence in Him has only been strengthened by indulging these questions. I am more assured of His existence, His power, and His goodness than ever before.
I encourage you to challenge your understanding of the Trinity by explaining it to someone else. That person could be a child or an adult, a Christian or an unbeliever, a close friend or a total stranger. This isn’t a pass-fail test to see whether or not you “get it.” It’s a starting point to see what unanswered questions you may have and not even be aware of. Questions are wonderful. They are fodder for spiritual growth! I pray you won’t be discouraged by what you don’t yet understand, but rather encouraged to grow in your knowledge, your understanding, and your worship of God.
Father God,
Your ways are so much higher than my ways. There is so much about You that I don’t understand, yet You don’t give up on me. You are so patient with me. Please continue to grow me. Please strengthen me through the power of Your Spirit in me to comprehend the breadth and length and height and depth, and to know love of Christ that surpasses knowledge, that I may be filled with all the fullness of God.
In Jesus’ name,
Amen.
