Read Exodus 18, Job 36, and Psalm 66.
This devotional is about Exodus 18.
Whatever his background and beliefs, Jethro heard of God’s deliverance for Israel from others (v. 1b) but Moses described what happened personally (v. 8). Moses did not just describe the miracles and the plagues God had used to Jethro; according to verse 8b Moses also told his father-in-law “about all the hardships they had met along the way and how the Lord had saved them.” This would include the food and water miracles as well as God’s deliverance from the Amalekites which we’ve read about over the past few days. All of this was more than enough evidence that the God of Israel is true.
Jethro’s confession of faith in verse 11, “Now I know that the Lord is greater than all other gods…” may sound like the words of a man who believes in many gods with YHWH being the best, but it is actually a common OT way of expressing true faith. Couple that statement with the fact that Jethro “was delighted to hear about all the good things the Lord had done for Israel” (v. 9) and that he “brought a burnt offering and other sacrifices to God” (v. 11) and it seems clear that Jethro was truly converted at the time described in this chapter.
Moses’s testimony of God’s work was a powerful instrument in the conversion of Jethro. Have you considered how God might use your testimony to save others? Not just your testimony about how God saved you, but also of the other things he has done in your life? Think about how your salvation and walk with God has impacted your life, then be ready to share that whenever the door opens.
