You don’t have to be perfect, or even good; just be faithful, and then let God take it from there.
In Do Your Best and Trust God for the Rest, popular author James W. Moore talks about the idea that God doesn’t expect us to be perfect. Instead, God simply asks us to be faithful, and then God will do and be what we cannot. Moore, through personal experience, shares how “God has the power to redeem! God can take our weaknesses, our foibles, our feeble efforts and redeem them and use them for good. God can take our defeats and turn them into victories!” This book contains a discussion guide.
