Men should be accountable to other men in order to avoid a hard heart. Hebrews 3:13 “But exhort one another daily, while it is called today, lest any of you be hardened through the deceitfulness of sin.” Desiring God ministries has a form that all of their pastors fill out each week when they meet together. All would agree that it is not the filling out of the form that matters but the heart behind it. We all desire to be true and holy to our God.
Although this form is directed at pastors of the church where Piper is senior pastor it can be modified for men who want and desire to be pure in their walk with God.
Do not think that you are too big to fall into sin. Just because you have a daily study habit or some other method that you cannot fall into the trap of sin. Be on guard and seek to be holy before the Lord.
