first you have to believe he will.then you walk in light as he is in the light.get filled up with the word of God.you must have the Holy Spirit.read John ch. 6 and 7. ch. 6 shows ch. 7The Lord showed that they compliment each other.In Jn. 6:35 it would be easy to miss the part where it says shall never thirst. it is looking in the never hunger that stands out.it is those who both hunger and thirst that will be filled . it's not talking about natural food. it is clear that no specific person, but all can come to get this spiritual food and drink. v.47 also shows those who believe.Jn. 7:31 many people believed on him.v.37 now we see repeated, if any man thirst, like in ch.6v.38-39 the belly full of waters comes from being baptised in the Holy Spirit which he says here is given.this is the only way to satisfy that thirst is to have him living in you.
