Religiousness gives an uncomfortable feeling to a person's heart, because he thinks that he is going to heaven but those (also religiousness) who do not believe in Jesus are headed for eternal damnation. A religious person has a burden for saving people, and it's a heavy load for him.

Biblical faith trusts in Jesus and the work of God's word and the work of the Holy Spirit, because God Himself is the one that gives faith to a person's heart through the testimony of the Holy Spirit and the word of the Gospel. Biblical faith rejoices in salvation, but at the same time has a healthy sorrow for the godless, however trusting God's power and goodness that draws a person to repentance and salvation. Biblical faith does not carry the load for saving the world, but rather leaves that to God, for He is the only one who can save a person. Biblical faith doesn't share Jesus to the godless because of having a burden for their salvation, but because God's Holy Spirit gives him love for the godless and through Biblical faith he shares and speaks of the Lord Jesus and salvation.

A religious person has doubts about his own salvation because he sees himself as lacking and unworthy in the eyes of God, and because of this he does religious works trying to make himself worthy. It may come to pass that sooner or later- as it has happened to many- he will grow tired of performing religious works and will give up the practice of his religiousness (faith).

A person with Biblical faith receives in his heart the certainty of faith and salvation through the testimony of the Holy Spirit, that God has saved him, and he shall be saved through God's grace by believing in the Lord Jesus, because of his work . This same thing will happen to everyone who has Biblical faith, whether he be a child, a teenager or an adult. Through healthy growth in the faith this thing will get stronger and stronger and he will learn in his heart, through growing in the faith, to understand that because of what Jesus did, God will save him through faith without his own works and accomplishments.

However, a very small child doesn't need to understand this, because when he has enough age that he can personally understand good and evil, he can receive faith and be saved by God's grace through faith in the Lord Jesus , and then he will receive the certainty of faith and salvation in his heart that will grow and get stronger day by day in his heart.
