The contrast is between the righteous and the wicked. God delights in the righteous (v. 20) and delivers them from lust (v. 6), death (v. 4), trouble (v. 8), and gossip (v. 9). God also delivers their families (v. 21).
God guides the upright in their integrity (v. 3) because they desire what God desires (v. 23). They sow righteousness (v. 18) and flourish like a healthy tree (vv. 28, 30). The upright are a blessing to others (vv. 10–11), and they gain a sure reward (v. 18).
