'By Faith' in the Bible

For we conclude that a person is made right with God by faith [in Christ], apart from [obedience to] the requirements of a law [or, the law of Moses, See verse 20].

since there is [only] one God, who makes the circumcised ones [i.e., the Jews] right with Him by faith [in Christ] and the uncircumcised ones [i.e., the Gentiles] through faith [in Christ].

For this reason, the promise [i.e., of being made right with God] comes through faith [in God], according to His unearned favor, so that it may be [given] with certainty to all of Abraham's descendants. The promise is given not only to those [who live] under the law [i.e., the Jews], but also to [all] those [who live] by faith, like Abraham. Abraham is the [spiritual] father of all of us [believers],

Why? Because they did not [attempt to do it] by faith [in Him], but by trying to fulfill all the requirements [of the law]. So, they stumbled over "the stumbling stone," [i.e., the Jews refused to become obedient to Christ. See I Pet. 2:6-8].

But the [means of] being made right with God by faith [in Christ] is described in the Scripture this way [Deut. 30:12-13], "Do not ask yourself, 'Who will go up into heaven?'" (in order to bring Christ down [to earth]).
