[John 14:20 CSB] "On that day you will know that I am in my Father, you are in me, and I am in you.

The day that Jesus appeared to the disciples He declared that He was alive. And on that day they learned that Jesus and the Father are one. The day we accept Jesus we experience Jesus in us. We all were in Jesus' heart on the day He was crucified on the cross (Good Friday). He did it for us, for the world. Today is the day of salvation. The bible talks about our salvation in the past, present, and future. We got saved. We are being saved. We will be saved. We are to live each day crucifying our flesh and picking up our cross and following Jesus. Make today count! (Ephesians 2:5, 1 Peter 1:8-9, Philippians 2:12, Romans 5:9-10)
