Your claim that your faith is the right one is supported by the Bible which requires said faith already.
We receive the
faith as a free gift from God as we are taught about God based on what is written in the bible. The bible presents divine truths, and the divine God imparts the
faith that convicts us of those truths so we may know for certain that the bible is true and is from God.
The
faith doesn’t come from the bible, nor is it
faith in the bible. The
faith comes from God and is
faith in God, not the bible. It can even be said that the
faith is the mind and intelligence of God within us.
This
faith is imparted to us in the form of a spiritual “seed” that grows within us. As this spiritual “seed” of
faith grows within us, our godly intelligence and ability grows "
until we all reach unity in the faith and in the knowledge of the Son of God and become mature, attaining to the whole measure of the fullness of Christ." - Eph 4:13.
If it was possible to impart a part of your mind within me, your mind within me would be
evidence or
proof of your existence because I would begin to know and understand for certain what you know and understand for certain by virtue of your mind and intelligence within me, but those who do not have your mind and intelligence within them would not know and understand as you and I do because they do not have the
evidence of you in them as we do. This is why we can begin to know and understand the things of God but others can’t, it is because we have the mind and intelligence of God within us in the form of the spiritual “seed” of
faith, but they don't.
The natural man does not accept the things of the Spirit of God, for they are foolishness to him; nor can he know them, because they (the things of God)
are spiritually discerned...But we have the mind of Christ. – 1 Cor 2:14-16.
Because
faith is the “
mind of Christ” imparted to us,
it is considered
evidence or
proof of God within us, because
it is God's mind and intelligence we have in the form of the spiritual "seed" of
faith. "
Now it is God who has made us for this very purpose and has given us the Spirit as a deposit, guaranteeing what is to come." - 2 Cor 5:5. As this spiritual "seed" grows within us, we continue to know more and understand more about God, and are able to do more for Him.
However, our words and our deeds will appear to others as “
foolishness” because they do not have the mind and intelligence of Christ in them as we do. “
The natural man does not accept the things of the Spirit of God, for they are foolishness to him.” – 1 Cor 2:14.
This is also why all that I just wrote will be considered “
foolishness” by many who read it, including you. But all such criticisms are
predicted in the bible and will only help to confirm its truths and add to the validity of it.
