During the Christian walk we have to stand up to sin and the enemy, Satan himself. We must stand steadfast just like Noah did. Even if none will follow, we remain strong in our faith in God. Noah was mocked for his faith an we too will suffer mockery in a society that hates God.
It is very important that we commit Scripture to our mind and heart. In the Psalms the Word of God teaches us to hide Scripture in our hearts so we might not sin against God. Peter tells us to always be ready to give an answer for the hope that is in us. To depart from the path of sin is a sign of spiritual maturity and growth. So flee to God and Satan will flee from you.
