Absolutely. We are saved by Grace through faith which the Holy Spirit engenders in us. But Jesus said to Nicodemus: "You must be born again." Why must we be born again? To achieve salvation and attain a personal relationship with Christ. Being born again results in a dramatic change in our lives. We enter the upside/down world of true Christianity.
Mat 10:39
“He who finds his life will lose it, and he who loses his life for My sake will find it.
Mat 20:16
“So the last will be first, and the first last. For many are called, but few chosen.”[fn]
The almighty God, Lord of the universe washed his disciples feet.
Mar 10:21
Then Jesus beholding him loved him, and said unto him, One thing thou lackest: go thy way, sell whatsoever thou hast, and give to the poor, and thou shalt have treasure in heaven: and come, take up the cross, and follow me.
Why do you suppose Paul said this if we punched out ticket to heaven 20 years ago when we shook the pastor's hand??
Phl 2:12
Wherefore, my beloved, as ye have always obeyed, not as in my presence only, but now much more in my absence, work out your own salvation with fear and trembling.
