No I think you got this alittle mixed up.
No man can unter unless he is first cleansed. How are we cleansed. By the work of God. (titus 3: 5)
it is not our works of rightiousness, But his mercy which saves us by the washing and new birth of the Holy Spirit.
which is what LT was trying to show you
If he was referencing John 3 the water is indicative of being born of a woman I.E> Her water bursts...
In order to enter the kingdom of God you must...
1. Be born into this world and or conceived
2. Be born of the spirit<--born again in Christ by faith thru grace because of mercy I.E. Saved, redeemed, justified and all of the other words that biblically apply unto the saved children of God
Obviously children that have not reached whatever age (moment of realization) of accountability are safe under the blood as well as children who die before an ability to make a decision of faith to wit David's 1st born son from Bathsheba..I will go to him (David stated) concerning his death....
When the Exodus came it was blood (Passover) before water Red SEA
When Jesus was pierced it was blood before water
Someone saved it is blood before water
The putting the water before spirit in John 3 tells me it is something other than baptism and context as well as the fact Nicodemus was viewing it from a physical birth as well seems to indicate context....
