(Luke 11:9-10) ¶ “So I say to you, ask, and it will be given to you; seek, and you will find; knock, and it will be opened to you.
10 For everyone who asks receives, and he who seeks finds, and to him who knocks it will be opened.
Pray, keep on praying and don't give up.
There is nothing more important. There is nothing more beneficial. There is nothing more productive.
Sit down and spend some time eyeball to eyeball with God.
Seek His glory, His will, His kingdom. Wrestle with Him over the difficult circumstances of your life. Throw yourself repeatedly into His arms. Surrender to Him again and again.
Confess your weakness, your shortcomings, your failures, your sins. (He knows about them - but you might be ignoring them yourself.) Pray that He would cleanse you and restore you and be vindicated in your new obedience.
Submit yourself to God in humility - then you can cast all your care on Him and take comfort in the fact that He cares for you.
Pray as if your life depended on it. In many ways it does.
