One of the first, strange Christian terms I remembering hearing is "accountability partner"? What, exactly, is this? Frankly, the term can seem a little creepy.
But if you know your heart, you know there is absolutely nothing creepy about having a fellow Christian in your life to help you battle sin. Paul Tripp in his book, Instruments In the Redeemer's Hands has a great chapter on accountability and a great section that explains what it provides:
1) Accountability provides structure. Because life can be so busy, it is helpful to have a person or a group of people with whom you regularly discuss life's most important matters.
2) Accountability provides guidance. Practical, personal input is needed if we are to grow in Christ-like living.
3) Accountability provides assistance. Sometimes we need more than "input." We need help. We need someone to literally take us by the hand and walk us through a situation. Accountability can make that happen.
4) Accountability provides encouragement. It's not all about being rebuked. Sometimes it's about being reminded of ways the gospel is actively at work in your life.
5) Accountability provides warning. When someone is rebelling against necessary change, accountability is like a stop sign. To ignore that stop sign is to enter the danger zone.
Whether you like the term or not, do you have an accountability partner? If not, why not? Is it for lack of time, lack of interest, lack of conviction of sin? Look for someone that God may have already have put into your life who can encourage you to follow Jesus more closely.
