Reading for October 20th

Read 1 John 1.5-2.27 Two tests. 
In verses 1.5-2.17 The ethical test.
Expressed as walking in the light, testing six of the seven assertions made
by the opponents (1.6, 8, 10; 2.4, 6, 9; see 4.20).
In verses 1.5-2.2 Walking in the light: sin and sinlessness.
In verse 5 God is light: see 4.8 and Jn 4.24.
Light is the self-revealing character of God.
In verse 6-7 if we say: a formula introducing the first three assertions
(1.6, 8, 10) of the opponents.
Walking in the darkness falsifies the claim because God is light
(1.5; see Jn 3.19-21; 8.12; 11.9-10; 12.35-36).
Lying (see 2.4) is opposed to doing what is true (see Jn 3.21).
The blood of Jesus (see 5.6-8) cleanses us from all sin,
(see 1.9; 2.2; 5.16-17) through sacrifice.
In verses 8-9 we have no sin: self-deception (see 1.10).
The way to deal with sin is not denial but confession.
Faithful and just: better, "faithful and righteous" (see 2.1, 29; 3.7).
In verse 10 we have not sinned perhaps refers to past behavior;
it is unclear how this differs from the second assertion.
In verses 2.1-2 the provision for one who sins is the presence of the advocate,
elsewhere used only of the Holy Spirit (see Jn 14-16).
Jesus is also the atoning sacrifice (see 4.10; Lev 16.16, 30)
for the sins of the whole world (see 4.14; compare Jn 1.29).
