The faith that really works is the faith that does work. It is living, active and productive faith. Dormant or idle faith on the other hand is dead and produces no result. That is the faith that says "I believe in God" or "I know God" but continues in disobedience to the word of God. Therefore to him that knoweth to do good, and doeth it not, to him it is sin - James 4:17. 

Faith makes the believer bigger than their actual appearance. All that you need to do exploits in the kingdom of God is faith as small as a mustard seed. Every believer has this size of faith but unfortunately many are not aware of this fact. When his disciples asked the Lord to increase their faith, he told them all they needed was faith as small as a mustard seed - Luke 17:6.

A baby that is born complete with all the members of the body does not immediately know how to use those members to their full potential. For instance, he may hear the sound of spoken words but is unable to make sense out of what is being said. Also, though the baby may make sounds with his mouth, he'll not be understood by grown-ups. The newborn baby needs food for physical growth and development.

At salvation a sinner is translated from the kingdom of darkness into the kingdom of light, where he now lives as a child of God. Every child in the kingdom of light is meant to pass through the process of transformation that takes them from childhood to maturity. This process is necessary to make us mature sons and daughters that are able to follow the leading of the Holy Spirit - Romans 8:14. 

While the disciples who witnessed the ascension of Jesus Christ, stood gazing into heaven, they were informed by two angels, that the same Jesus will come back again. Since then, many deceivers have presented themselves to the world as Jesus. But we are expecting the same Jesus that ascended into heaven, to come back in like manner by descending from heaven to rapture his bride: "for the Lord himself shall descend from heaven ..." - 1 Thessalonians 4:16-17.
