It is important to note that Jon is drawing from John 13:1-11 - where Jesus washes the feet of the disciples.
First, much of the Christian life is spent trusting Jesus now and understanding him later. Jesus typically does not feel it necessary to explain on the front end why he is doing something the way he is doing it. And, like Peter, when it looks wrong to us, we are tempted to object to the Lord’s will.
God understands and is patient with our confusion and even our deep wrestling or grief. But he wants us to trust him and not grumble. God’s ways are not our ways (Isaiah 55:8). His purposes for bringing or not bringing certain things to pass often extend far beyond us—maybe even generations beyond us.
So during those times we need to remember Jesus’ words to Peter: “What I am doing you do not understand now, but afterward you will understand.”
Second, what Jesus is bringing about in the sometimes confusing, sometimes very painful work he is doing in our lives is sanctification. He is washing our feet. He not only bathes us, completely removing the guilt of our sin in his cleansing work on the cross, but in love he keeps forgiving us (1 John 1:9) and disciplines us so that we will share his holiness (Hebrews 12:10-11).
Our understanding his purposes in a particular providence tends to be not as important to God as our trust in his character. So together let’s continue to “trust in the Lord with all [our] heart, and…not lean on [our] own understanding” (Proverbs 3:5). Because one day we will understand. And we will, with great joy, proclaim, “The Lord is righteous in all his ways and kind in all his works” (Psalm 145:17).
