about us

How we got Started

Honestly, we’re still getting started! Even though we began in 2005, this ministry has been a part-time endeavor and a labor of love for God and His people. We are a group of women who use the gifts God has given us to deliver training and encouragement to His children. We got started initially when the training company I (Nina) was working for offered me a position that would require tutors and baby sitters for my kids so I could manage more trainers and teach more classes. I was sensing that God had a different plan for me, and that NOW (2006) might be the time to give life to the dream He placed within me fifteen years earlier. I had deep desire to equip God’s people to “make a greater impact” in their circles of influence. So, I quit my job and started this ministry.

Early on, I sensed God’s leading to write Daughters of Sarah. The neat thing is that, in doing so, He created within me a desire to “get it right at home.” The principles from that course helped create a right environment for our team. We put the needs of our team and their families ahead of the needs of the ministry – for example, I limit out of town speaking engagements to 4-6 times a year. We take time off in the summer. We try to be an encouragement to each other as friends first. This also fits with the Daughters philosophy, to encourage women to deeply connect with each other and do life together.

The Respect Dare evolved out of Daughters of Sarah, then our Strength & Dignity eCourse. Recently, we’ve moved into online live classes and life coaching.

Our Mission

Greater Impact Ministries, Inc. is a biblical training organization purposed to equip men and women to make a greater impact in all that they do, for the Lord Jesus Christ.

As an organization, first and foremost, we are committed to God. We seek to follow His direction and timing, while pursuing excellence in all that we do to glorify Him. This applies to how we deliver our courses, select mentors and coaches, and manage the day-to-day business of the organization. All of our ministry team members are expected to develop and pursue their relationship with Jesus on a consistent basis. We are stewards with the resources God provides for our ministry.

Greater Impact Ministries, Inc. is a non-denominational, tax-exempt, non-profit training organization.

What we Believe

1. We believe in one God, holy, infinitely perfect, and existing in the Trinity of unity in God the Father, Jesus the Son, and the Holy Spirit.

2. We believe the Bible is the inspired work of God. We believe it is a living document through which God communicates to His people.

3. We believe all men and women are born sinful and are no longer slaves of sin after they become saints by accepting the saving gift of Jesus Christ and making Him Lord of their lives, confessing this with their mouths.

4. We believe marriage is instituted by God, and is intended to represent Christ’s relationship with His church.

5. We believe marriage is between one man and one woman, according to the Scriptures.

6. We believe God’s greatest commandments are to love Him and love others, regardless of their religious affiliation (or lack thereof), gender, age, ability/disability, sexual orientation, or other backgrounds.

7. We believe we are here to learn to love others well, and not to judge, but also to teach the truth of the Bible.

8. We believe all people are on a spiritual journey.

9. We believe judgment is reserved for God alone and Christ when He comes again.

10. We believe the Scripture teaches women are of equal value to men, and both are created in the image of God.

11. We do not ascribe fully to labels (pre-destination, complementarian, etc.) but encourage people to discover for themselves what God would have for them through the Bible and their relationship journey with Him.
