In context he was going to wash his feet then Jesus answered him, “What I’m doing you don’t understand now, but afterward you will know.” In the moment of our suffering or in our waiting for answers; we may not know what God is doing behind the scenes but believe that He is preparing you to grow in a deeper relationship with Him. For all the ones who are waiting on a answer or just going through it I encourage you not to lose patience but rejoice in the fact that He is sovereign. Commit your way to the Lord ; trust in Him, and He will act
Psalms 37:5 HCSB
