There is no connection either implicit or explicit in the text between what is "written on the hearts" and the image of God. The thrust of the text is that everyone stands guilty before God (Rom. 1-3). Even though the Gentiles have some knowledge of God through various natural means (the natural world and their conscience), the text declares that humanity has frustrated this purpose of God by its resistance and rejection. In so doing, it has not merely forfeited the knowledge of God accessible to it, but God has traditionally withdrawn this knowledge. God has "given them over" to a dark mind. His revelation is now that of a broken line. But they are potential he remains a relic of the direct knowledge of God through natural means, but it poses both a benefit and an indictment. The knowledge that people have does help them, but it also condemns them if they don't follow it. In other words, God has nowhere left himself without a witness, and decisions in his direction are always possible outside of special revelation, but God is now obscure to humanity.
Therefore, Paul is not specifically talking about morality, because being good is not the path to God, and Paul doesn't want to get close to suggesting anything that could be interpreted that way. On the other hand and by the same token, there any knowledge of right and wrong shows that God has put some notion of himself out there to be perceived. That they could know enough to do right some of the time render some without excuse for never doing wrong. Only when God’s law is fully written on the heart in Christ (Rom. 8.2; Jer. 31.33) will it be internalized enough for people to live out God’s righteousness.
John Aloisi explains: As Paul is intending and will later explain more fully, the conscience operates in a purely mechanical manner. It does not involve a distinct ministry of the Holy Spirit. A conscience may be educated by special revelation or weekend by faulty information. It may be pragmatically molded by social custom and civil law, and it can be seared as a result of habitual disregard (1 Tim. 4.2; Titus 1.15). People may feel guilty when they are rebuked by their conscience, but such guilt is a response somewhat like that of the tactile nerves when they cause a body to recoil from pain. The human conscience keeps people from progressing in sin as readily as they would if they never experienced guilt, but it should not be confused with the Holy Spirit’s work of conviction. Conviction is a special work of the Holy Spirit which is always performed in connection with special revelation. Conviction involved convincing sinners of things which could not be known apart from special revelation. Therefore during the current age conviction may only be experienced by those who have some contact with the Word of God.
So, yes, this phrase about "written on the hearts" does pertain to some inherent knowledge of right and wrong, but Paul's point is not morality. It's salvation. There is no connection here, however, with the image of God.
