All good evangelism is ethical, but the question is whose ethics are moral for all creation. Psalm 119 reminds us that if we place God's word to live in our heart (our moral / ethical center) than we will not sin against God or fall to far from God. Jesus in the gospels reminds us that sin comes from our heart, and it's this point of departure that I ask whose ethics and morals are good to follow. With so many different beliefs and religious practices in our society who is to judge?
Speaking for myself as it pertains to Psalm 119, I find myself wanting, trying to live according to God's will in my life. I let my morality become shaped by the biblical example of the historical Christ. I lve by the fact that I am to love my neighbor which is how I show love to God, this is the word implanted in my heart which grounds me and keeps me from falling away form God.
1Blessed are those whose ways are blameless, who walk according to the law of the LORD.
2 Blessed are those who keep his statutes and seek him with all their heart—
3 they do no wrong but follow his ways.
4 You have laid down precepts that are to be fully obeyed.
5 Oh, that my ways were steadfast in obeying your decrees!
6 Then I would not be put to shame when I consider all your commands.
7 I will praise you with an upright heart as I learn your righteous laws.
8 I will obey your decrees; do not utterly forsake me.
9 How can a young person stay on the path of purity? By living according to your word.
10 I seek you with all my heart; do not let me stray from your commands.
11 I have hidden your word in my heart that I might not sin against you.
12 Praise be to you, LORD; teach me your decrees.
13 With my lips I recount all the laws that come from your mouth.
14 I rejoice in following your statutes as one rejoices in great riches.
15 I meditate on your precepts and consider your ways.
16 I delight in your decrees; I will not neglect your word.
