We need the faith of Jesus , that is, the faith Jesus demonstrated during His ministry here on earth. For I have come down from heaven, not to do My own , but the of Him who sent Me. The faith of Jesus enabled Him to trust His Father entirely and to obey Him in all things. This is the faith we need. Many times in his epistles, the apostle Paul explains the precise role of good works in the life of the believer.
Good works demonstrate the good health of our faith.
Good works help us to earn our salvation. Good works make us appear righteous before God. Good works erase our sins and purify us. Faith also allows us to take seriously God's warnings, and therefore to make the necessary decisions without delay. The First Epistle of Paul to Timothy deals with the subject of genuine faith.
