As to "faith." I believe there are two types of faith. The natural/human faith we are born with, which all men have. And the supernatural faith we receive from the Holy Spirit's indwelling presence.
The natural/human faith is enough for us to hear the Gospel, call of the Holy Spirit, and believe in Christ, and seek Him. The supernatural faith we receive is the faith that is strong enough to sustain us in times of trials and tribulations. The natural/human faith will never be strong enough to do that for most people I believe. I have seen this many times in people in my life, when they put their natural/human faith in something or someone of this world, only to be utterly let down, and it causes them to lose faith, and even lose hope.
Just my thoughts about "faith."
How would you like me to show you just how GODLY that teaching and thought of you are, with a Verse in the Bible teaching exactly that.
Let me first share how God works as short as I can.
Every saved person was logged into the book of life before the earth was formed. Time does not exist with God and our human brains really has to put a lot of energy in this concept to just try to understand what would it be like if there is no time. It will be like Everything happening at the same split second FOREVER. So Right now God writes our names in the book, but also right now it is the end of the earth, but also right now Jesus dies, and was resurrected... WOW I am already dizzy!
But Jesus said to His disciples..
receive the Holy Spirit and he blew over them. Then some time later He walks with them and says:
There are still many things I want to teach you but you cannot bear it yet....
and He also says to them...
You shall receive power when the Spirit is come upon you...Even though He blew over them.
And we know when they were in the upper room on Pentecost, they were filled. This is Truth and also in order of events, and then we see this verse and everything comes together....
Rom 1:17 For therein is the righteousness of God revealed from faith to faith: as it is written, The just shall live by faith.
The disciples dropped everything and followed Jesus... this will not happen without FAITH! But they had NO FAITH when they stuck with Him and could not even stand a storm, or heal a boy, or believed it was Him resurrected. But AFTER they were filled with the Holy Spirit they were TRUE MIRACLE WORKERS FULL OF FAITH ... same as Stephen, And Stephen, full of faith and power, did great wonders and miracles among the people.
The faith that saves us, is in power nothing less than the works of FAITH, God bless us with. However the Faith may fall short in the first process but NEVER in the second! With the Spirit comes the unwavering faith Jesus had. Jesus said if you had faith of a mustard seed ... well the Spirit comes with the whole TREE!
