Cultivate Your Calling in Each Stage of Life

Angie Ward discusses cultivating leadership amid ever-changing responsibilities.

Angie Ward, author of the recently published I Am a Leader, has 30 years of leadership experience in diverse roles in ministry. I was excited to talk with Angie about how our calling shifts through the various seasons of life.

How can a woman’s calling change over the course of her life?

Sometimes we think as young women that we have one calling, and that’s it. We just have to find it, and we put so much weight on that one thing. But for most people, it changes how it looks and how it’s lived out based on seasons of life and age. Our calling can also change because we change. Who we are, our gifts, our passions. And that’s okay.

For me, I started out in youth ministry, but then God expanded it. It didn’t shift entirely. It was still vocational/occupational ministry, but it went to more broad ministry—leadership and to leadership development. When I was 22, just out of college, I didn’t have the experience or the wisdom to train other leaders. I was just working with students who were sometimes only four years younger than me. The Holy Spirit moves and flows. Working with kids in children’s ministry at your church may make you aware of the needs of foster kids. It opens a door to a whole new thing.

How can we discover what our calling is today?

Cultivate an ear for the Holy Spirit—a heart and a mind that's receptive, that knows the Shepherd's voice, and a heart that's obedient and responsive to whatever it is during that season. A lot of times we get focused on the wrong question: What is it? We focus on trying to figure out the it. Instead, the real focus should be on cultivating our relationship with Jesus and walking with him. We want steps to cling to. If I ...

What Is Calling?

Defining this “super-spiritual” word

I can’t remember when I first heard the term calling. I just know that by the time I got to seminary at age twenty-four, I was using the word to describe why I was there and why I picked the particular seminary I attended.

Why did I come to this seminary? Simple. “God called me here,” I replied, to knowing nods and murmurs.

By then, I had marinated in Christian subculture for long enough that I think the word had just seeped into my vocabulary. Growing up in church, I heard missionaries talk about how they were called to specific countries and people groups. I heard my pastors talk about how they had been called to (or away from) our church. In college, I probably heard chapel speakers talk about the importance of following God’s call. I also talked with friends who had been dumped by a boyfriend or girlfriend who felt God “telling” them to do it. (Of the validity of that last “calling,” I was often skeptical.)

As a Christian, calling definitely seemed like a super-spiritual word. A “call” from God implied a close relationship with him. Who wouldn’t want to hear from God directly? Plus, using the word calling raised the speaker and his or her behavior above dispute. How do you argue with someone who claims to act on the voice of the Lord?

As I continued through seminary and then into vocational ministry, I heard and used calling frequently. I heard it used in so many ways, however, that I wasn’t actually sure what it meant. And as I progressed through different stages of my own life, I continued to wrestle with calling: both what it was in general and what mine was.

So, what is calling, really? Can it be defined?

In Scripture, calling is a ...

When Your Calling Is Challenged

As hardships come, you have 1 of 3 options.

This was not how things were supposed to work out.

Every night for a year, my husband and I had prayed that God would direct us to the right place in his right timing. Based on our own prayers as well as confirmation from others, it seemed that the “right place” would be a church where Dave could serve as senior pastor, giving him more opportunities to exercise his gifts of preaching and shepherding. Now that we had two little boys, we also desired to be closer to family. We told God that we would go anywhere he led us (and we meant it!), but that we would love to end up somewhere in the southeastern United States, ideally within three hours of Dave’s parents.

We explored options around the country. We prayed, waited, and sought counsel from wise and mature believers. We continued to serve faithfully in our current ministries. We prayed and waited some more.

Twelve months later, our little family made the 1,200-mile journey from Minnesota to our new church in North Carolina—just two and a half hours from our sons’ beloved Nana and Papa—where Dave would serve as lead pastor. We felt God had clearly answered our earnest prayers, as evidenced by all sorts of confirmations that seemed like way more than coincidence. I mean, at the boarding gate for our flight home from our interview weekend, we discovered that our pilot “happened” to be a friend who first came up to Dave a year earlier and said he felt God was preparing my husband for a lead pastoral role!

We were over-the-moon excited. We felt we had come home, and we thought we’d be at that church and in that city for life.

Yet three years in, our dream situation had turned to a nightmare. Our church was slowly dying, our marriage ...
