You need to persevere so that when you have done the will of God, you will receive what he has promised. Hebrews 10:36
Waiting is hard to do. Waiting for an 'overdue' birth past the date the baby was forecast. Waiting for your garden to grow. Waiting for a lost pet to return home. Waiting for a prodigal child. Waiting to see if you get into a certain college or accepted to medical school. Waiting for an answer to prayer.
In the Bible there were many scenarios where God required patience and things got rather messed up when someone jumped ahead and tried to orchestrate things themselves take Abraham and Sarah waiting for a baby God promised even though the mother to be was well past child bearing age. (See Genesis Chapter 12).
What is it you have a hard time waiting on? As hard as it may be, try to be still and allow God to work as He has planned. Don't jump ahead and mess things up. God has a plan.
PRAYER: I pray and pray yet nothing changes Lord. I don't want to jump ahead of what your plan is. Give me strength to be still when I would rather be anxious. In Jesus' name. Amen.
