This appears to be random amidst the events that are unfolding. Lazarus dies, Jesus wants to wait a while, then He wants to go, then the disciples ask if He's sure because some people wanted to stone Him. But then He drops verse 9 and 10 on them. Those verses take me back to
“3 Those who are [spiritually] wise will shine brightly like the brightness of the expanse of heaven, and those who lead many to righteousness, [will shine] like the stars forever and ever. (AMP)”
God will open this up more, but I'm seeing some take aways; Pray for spiritual wisdom. Where does that come from? For the LORD gives wisdom; from His mouth come knowledge and understanding; (see Proverbs 2 : 6) Pray to be so filled with light, others ourselves and others no longer stumble in the dark. Where does the light come from? “Again Jesus spoke to them, saying, “I am the light of the world. Whoever follows me will not walk in darkness, but will have the light of life.” (see John 8:12) We pray to walk in Your Light, oh Lord!
