Evil and sin were not part of our original design. We may equate sin with human nature, but the reality is that God did not create us to rebel against Him. Sin is not our natural state.
We were created to glorify God and live in fellowship with Him. I believe that sin becomes part of our lives when we lose sight of God's purpose for our lives. Purpose is one of the ways God helps us to remain on the narrow road that leads to Life. Erwin McManus wrote; “Sin is what happens when we have too much time on our hands and too little purpose in our lives” (Uprising; p. 186).
When we begin to really live out our purpose what we discover is that sin becomes an obstacle to what accomplishing what God has called us to do. When we are surrendered to God's purpose then we discover that we will reject things that are detrimental to accomplishing that purpose. On the other hand if we are not dedicated to God and His purpose for our lives we will be easily persuaded by things that will take us farther and farther away from where God wants us to be.
Yet it is not always easy to understand your purpose. Part of the problem, I believe, is that purpose comes in a couple different forms. The type of purpose we ultimately want is our grand life purpose. The type of purpose which will define our lives. Abraham’s purpose was to become the father of a great nation; Moses’ purpose was to lead Israel out of Egypt; and Paul’s purpose was to be the apostle to the Gentiles. We long to have that type of life defining purpose for our lives.
Before we arrive at our life defining purpose we must first live a life of faithfulness. This is the second form of purpose: the everyday purpose. It is through a life of faith that God prepares us for the grand purpose of our lives. It builds the character we need to accomplish the purpose God has given to us. Our grand purpose in life demands that we have a Christ-like character. Without this type of character we will fail.
While waiting around for our grand purpose to show up we often neglect the everyday purpose that every Christian has: to live by faith. The result is that rather than being prepared to live out the grand purpose of our lives we get distracted by the things of this world. We are not good stewards of the gracious gift of time God has given to us.
Think about what the apostle Paul wrote:
Look carefully then how you walk, not as unwise but as wise, making the best use of the time, because the days are evil. Therefore do not be foolish, but understand what the will of the Lord is (Ephesians 5:15-17; ESV).
To make the "best use of the time" (literally as we "redeem the time") means that we live faithful lives in whatever situation we find ourselves in . We do this by seeking and doing God's will. It is through understanding God's will, that we begin to catch a glimpse of God's ultimate purpose for our lives.
Purpose does two things when in comes to combating sin in our lives. First, it gives us a motivation to fight against any obstacle that might get in our way of completing God's will. Second it fills our time with activity so we have less to waste on sin. Purpose is a powerful weapon in our fight against sin.
