Notice Jesus words concerning the foundation. He said man was to lay a foundation UPON a rock. And we know that Jesus is the rock. So what is the foundation that must be laid upon Him? Jesus explained. Those who hear and do what He says are laying a proper foundation upon Him.The foundation is Christ.
You are either BAPTIZED into christ. Or your baptized INTO water.
I was baptized into Christ by God himself. I have a sure foundation.
"Whosoever cometh to me, and heareth my sayings, and doeth them, I will shew you to whom he is like:
He is like a man which built an house, and digged deep, and laid the foundation ON a rock: and when the flood arose, the stream beat vehemently upon that house, and could not shake it: for it was founded upon a rock.
But he that heareth, and doeth not, is like a man that without a foundation built an house upon the earth; against which the stream did beat vehemently, and immediately it fell; and the ruin of that house was great." Luke 6:47-49
It is due to one's trust in Jesus that individuals believe and accept His life giving message first presented by the Apostle Peter on the Day of Pentecost. This truth coincides with Hebrews 5:12-6:2
