A better translation of the word corruption is decay. When we come to understand that the entire creation is waiting for the manifestation of the sons of God to remove it from a state of decay, we realize that the theory of evolution has no merit. For evolution suggests that the creation is growing rather than decaying. Faith is the basic ingredient that Christians must have and it is a powerful force in the hands of a believer. It appears that the depth of our commitment and courage in times of distress is equivalent to the degree of faith that we have in Him.
Faith comes first, then love.
We must first have the faith that God exists and that He is the rewarder of those who diligently seek Him. Then after we begin to diligently seek Him and begin to apply His holy and righteous laws into our life, we find that our love for Him increases. Just as in a successful marriage, over time the love for our partner grows stronger and stronger. And as that love grows, our willingness to sacrifice for each other also grows. As our love grows, so does our commitment to each other - also true of our relationship with Jesus Christ and the Father.
