Ephesians 4:1-3 is something that I think "grace preachers" seem to forget. Paul, a man God chose to use to write like half the New Testament, urges the Ephesians to "walk in a manner worthy of the calling to which you have been called..." To me this is a command to do something in response to God's gracious choosing of you. We are to "walk in humility and gentleness, with patience, bearing with one another in love, eager to maintain the unity of the Spirit in the bond of peace."
Quickly, "humility" should be a given if we understand the LACK of anything we've done to desire the gift of salvation. And "gentleness" would come as a result of this humbled life. "Patience" is something that will grow with our understanding of what a depraved place we've been pulled out of. We will be able to look at every situation that may cause frustration and the lack of patience and see that God has saved us from these exact situations simply because He desired to do so. Even situations with other believers, we can "bear with one another in love" if we realize our different levels of Spiritual maturity and the need to help one another through our spiritual growth. And if we can grasp this, "unity" will be achieved.
That was really too quick a break down to make much sense, the alarm for me to leave for work is BLASTING! More on these verse tomorrow, because I really do struggle with most of these areas.
