Your pain is in your area of calling be a ministry

Hannah's prayer
10 In her deep anguish Hannah prayed to the Lord, weeping bitterly. 11 And she made a vow,saying, “Lord Almighty, if you will only look on your servant’s misery and remember me, and not forget your servant but give her a son, then I will give him to the Lord for all the days of his life, and no razor will ever be used on his head.”

I believe this was the first time that Hannah prayed to God and instead of asking for a child only, she committed to give back this child to the Lord. A child that she had waited for and longed for was now being released to God in faith.

This prayer turned to be about God and not Hannah.

Ministry is birthed through pain
This process was painful for Hannah. She experienced a lot of pain and torture from Peninnah. But one day, Hannah decided to release this matter to the Lord as a sacrifice to His Holy name.

Let us release our situations to God and tell Him that we are willing to serve Him through the experiences we have been through.

Rom 8:28
28 And we know that in all things God works for the good of those who love him, who[i] have been called according to his purpose.

God Himself assures us that everything will work for the good of the believers. Since God's desire is that many will love Him and come to the knowledge of His saving grace, we can trust Him to make beautiful our pain and minister to others through us.

God's grace is sufficient
2 Cor 12:8-9
8 Three times I pleaded with the Lord to take it away from me. 9 But he said to me, “My grace is sufficient for you, for my power is made perfect in weakness.” Therefore I will boast all the more gladly about my weaknesses, so that Christ’s power may rest on me.

This verse can be a beautiful prayer for ourselves and those going through seasons of pain that we may all emerge victorious through the trials.

Samuel, the son Hannah bore, became a great priest in Israel that God spoke through.
When Hannah allowed God to take over, God ministered to an entire nation.

God will use you to minister to nations, hold on.
