Salvation is accomplished by the almighty power of the Triune God. The Father chose a people, the Son died for them, the Holy Spirit makes Christ's death effective by bringing the elect to faith and repentance, thereby causing them to willingly obey the gospel. The entire process (election, redemption, regeneration) is the work of God and is by grace alone. Thus God, not man, determines who will be the recipients of the gift of salvation.
Faith is a living, bold trust in God's grace, so certain of God's favour that it would risk death a thousand times trusting in it. Such confidence and knowledge of God's grace makes you happy, joyful and bold in your relationship to God and all creatures. The Holy Spirit makes this happen through faith. Because of it, you freely, willingly and joyfully do good to everyone, serve everyone, suffer all kinds of things, love and praise the God who has shown you such grace.
Faith is the "eternal elixir" which gives life, power and action to the impulse of thought! Faith is the starting point of all accumulation of riches! Faith is the basis of all "miracles" and all mysteries which cannot be analyzed by the rules of science! Faith is the only known antidote for failure!
