Can we as humans impress God by the things we do?
Both the Old And New Testaments address this issue. In Job 35:5-8 we read;
“Look up at the heavens and see; gaze at the clouds so high above you. If you sin, how does that affect him? If your sins are many, what does that do to him? If you are righteous, what do you give to him, or what does he receive from your hand? Your wickedness affects only a man like yourself, and your righteousness only the sons of men.”
In Ephesians 4:30, Paul said we can grieve the Holy Spirit. The Greek word translated grieve means to make sorrowful or to offend. And in Romans 14:17-18 he wrote, “For the kingdom of God is not a matter of eating and drinking, but of righteousness, peace and joy in the Holy Spirit, because anyone who serves Christ in this way is pleasing to God and approved by men.”
Putting it all together it seems pretty clear. We can live in a manner pleasing to God or we can cause Him grief by the way we act. But ultimately our behavior, whether good or bad, only affects us and the people around us. God is not impressed.
