Two ways not to walk.

As sinners

Ephesians 4:17 “So I tell you this, and insist on it in the LORD, that you must no longer live as the Gentiles do, the futility of their thinking.”

The apostle charged the Ephesians in the name and by the authority of the Lord Jesus, that having professed the gospel, they should not be as the unconverted Gentiles, who walked in vain fancies and carnal affections. Do not men, on every side, walk in the vanity of their minds? Must not we then urge the distinction between real and nominal Christians? They were void of all saving knowledge; they sat in darkness, and loved it rather than light. They had a dislike and hatred to a life of holiness, which is not only the way of life God requires and approves, and by which we live to him, but which has some likeness to God himself in his purity, righteousness, truth, and goodness.

The truth of Christ appears in its beauty and power, when it appears as in Jesus. The corrupt nature is called a man; like the human body, it is of diver’s parts, supporting and strengthening one another. Sinful desires are deceitful lusts; they promise men happiness, but render them more miserable; and bring them to destruction, if not subdued and mortified. These therefore must be put off, as an old garment, a filthy garment; they must be subdued and mortified.

But it is not enough to shake off corrupt principles; we must have gracious ones. By the new man, is meant the new nature, the new creature, directed by a new principle, even regenerating grace, enabling a man to lead a new life of righteousness and holiness. This is created, or brought forth by God's almighty power.

Evangelism

The attitude of the average Christian today is relax and be raptured.  But He is coming… and when God gets angry you’ve no idea what it is.  Like a thousand volcanoes exploding.  He has appointed a day in which He is going to judge the world and the poor blind world doesn’t know much about it and the poor blind church doesn’t think much about it now.” – Leonard Ravenhall
