Well, I believe God has plans and we have freedom of choice about whether or not we participate in them. We are always free to say no and God can look for someone more amenable.
Psalm 138:8 says, The Lord will fulfill his plan/purpose for me. That's a twist we may not often think about - God working out his plans on our behalf. It's not all our responsiblity. God is helping to see that everything goes right. Sometimes you hear it said as, "If God called you to it, He'll see you through it." It's a reassurance that helps to keep us going. If you are walking in God's plan, he'll help; he'll walk with you. Verse 3 of Psalm 138 provides another assurance, When I called you answered me; you made me bold and stouthearted.
To all the bold and stouthearted people of God, carry on. God is with you to work out his plan on your behalf.
