You do not have to wish that you had more faith for whatever miracle you are asking God for right now. See Jesus on the cross for you, and the faith you need to face any situation or challenge will come into your life. Just look to Jesus! He is the author and finisher of faith. Faith comes by hearing and hearing by the Word of Christ. The more of Jesus you hear, the more faith rises in your heart. Get hold of teachings that preach all about Jesus and His finished work. There is no power in human philosophy or the traditions of man, but there is power in the gospel of Jesus Christ!
No man can deserve God's blessings by his self-efforts. It is not about our sacrifices. It is about His sacrifice! All God sees is the work of His Son, and by virtue of Jesus, all His blessings and His miracle-working power are already yours when you believe in His Son. Listen carefully to what Paul said to the Galatians who were depending on their self-efforts:
Galatians 3:5
... He who supplies the Spirit to you and works miracles among you, does He do it by the works of the law, or by the hearing of faith?
Look at all the people who received miracles from Jesus during His ministry on earth. Not a single one of them deserved it. They did nothing to earn their miracles. They simply received their miracles because of His grace. On the other hand, we don't find any record of those who were trying to deserve blessings from God - the Pharisees - receiving anything from Jesus!
