Jude 1:22
And you should show pity toward some people because they have doubts [regarding spiritual matters];
Galatians 4:20
But I would like to be present with you and change the tone [of my remarks], because I am very distressed over your condition.
Galatians 6:1
Brothers, if any one of you is overwhelmed by a [particular] sin, those of you who are spiritually minded should [attempt to] restore such a person [to faithfulness]. But do it in a gentle way, being very careful that you yourself do not become tempted [to get involved in any sin].
Hebrews 6:4-8
[These are people] who were once enlightened [by the Gospel message], who had experienced the gift from heaven [i.e., forgiveness, never ending life, etc. See Rom. 6:23], who had partaken of the Holy Spirit [See Acts 2:38],
James 5:19-20
My brothers, if anyone among you strays away from the truth [of God's inspired message], and someone brings him back [to it],
1 John 5:16-18
If anyone [of you] observes his brother [or sister] sinning [in a way that would not lead] to [spiritual] death, he should ask [God, in prayer, to help that person], and God will give him [spiritual] life, [that is], to such ones, provided their sin is not leading to [spiritual] death. There is such a sin that leads to [spiritual] death. [See Heb. 6:4-6; I Tim. 5:6; Heb. 10:26-27; II Pet. 2:20-22]. I am not suggesting that you should ask [God, in prayer] about such a situation.
Jude 1:4-13
For certain men have secretly infiltrated [your ranks]; they are men who had been written about long ago that they should be judged [and condemned] for perverting the unearned favor of our God into [a license for] living unrestrained, indecent lives, and who deny [the identity and work of] our only Master and Lord, Jesus Christ.
