We are NOT disconnected from Adam and Eve, although you may want to see us as simply appearing in the cabbage patch somehow. God created the human RACE, and we are part of it. The Jews certainly understood this. See Exodus 20:5 and Exodus 34:7, for example.
No I completely agree that we inherited their sinful nature but I disagree that we are unable to find favor with God. Genesis 6:8 Noah found favor with God. There are many other passages in the scriptures where men find favor with God.
“The LORD favors those who fear Him, Those who wait for His lovingkindness.”
Psalms 147:11 NASB
Very similar to Acts 10:35.
“My son, do not forget my teaching, But let your heart keep my commandments; For length of days and years of life And peace they will add to you. Do not let kindness and truth leave you; Bind them around your neck, Write them on the tablet of your heart. So you will find favor and good repute In the sight of God and man.”
Proverbs 3:1-4 NASB
“He who finds a wife finds a good thing And obtains favor from the LORD.”
Proverbs 18:22 NASB
“"Now therefore, O sons, listen to me, For blessed are they who keep my ways. "Heed instruction and be wise, And do not neglect it. "Blessed is the man who listens to me, Watching daily at my gates, Waiting at my doorposts. "For he who finds me finds life And obtains favor from the LORD. "But he who sins against me injures himself; All those who hate me love death."”
Proverbs 8:32-36 NASB
“Now therefore, I pray You, if I have found favor in Your sight, let me know Your ways that I may know You, so that I may find favor in Your sight. Consider too, that this nation is Your people." And He said, "My presence shall go with you, and I will give you rest." Then he said to Him, "If Your presence does not go with us, do not lead us up from here. For how then can it be known that I have found favor in Your sight, I and Your people? Is it not by Your going with us, so that we, I and Your people, may be distinguished from all the other people who are upon the face of the earth?" The LORD said to Moses, "I will also do this thing of which you have spoken; for you have found favor in My sight and I have known you by name."”
Exodus 33:13-17 NASB
“Now the boy Samuel was growing in stature and in favor both with the LORD and with men.”
1 Samuel 2:26 NASB
“Saul sent to Jesse, saying, "Let David now stand before me, for he has found favor in my sight."”
1 Samuel 16:22 NASB
“A good man will obtain favor from the LORD, But He will condemn a man who devises evil.”
Proverbs 12:2 NASB
