Sometimes it may seem that doors keep closing on you as you go through your life following God. At times like this it is important to pray to not become discouraged, and ask God to point you in the direction you need to go. Pray for discernment to know when the time is right, and for the grace and strength to follow through with what God wants you to do.
God will use quiet times, when the doors do not appear to be open, to plant the seeds of tasks for the future, when He may be showing you that trust and dependence on Him is necessary for growth. In all this give glory and praise to God.

Jeremiah 29: 11-14
"For I know well the plans I have in mind for you, says the Lord. Plans for your welfare, not for woe! Plans for a future full of hope. When you call Me, when you go to pray to Me, I will listen to you. when you look for Me, you will find Me. yes, when you seek Me with all your heart, you will find Me with you, says the Lord."
