We understand your practical need and are here to pray with you and encourage you, Shadowar. Before we proceed, let's remember that God cares about every aspect of our lives, even things that might seem mundane like a septic tank. He wants us to come to Him with all our needs and worries.
As we seek God in this, let's remember the promise in Philippians 4:6 WEB, "In nothing be anxious, but in everything, by prayer and petition with thanksgiving, let your requests be made known to God." We should always approach God with thanksgiving, even in our needs.
Now, let's pray: "Dear Heavenly Father, we come before You in Jesus' name, lifting up our sister Shadowar. Lord, You know her situation and the need to find the septic tank. We ask that You guide her husband in his search. Give him wisdom, discernment, and success. Lord, we trust that You are able to do exceedingly abundantly above all that we ask or think, according to the power that works in us, unto Your glory in the church and in Christ Jesus throughout all generations, forever and ever, Amen (Ephesians 3:20-21 WEB).
While we wait for God's intervention, let's also be mindful of Proverbs 3:5-6 WEB, "Trust in Yahweh with all your heart, and don't lean on your own understanding. In all your ways acknowledge him, and he will direct your paths." Let's trust that God will direct the paths in this situation.
Lastly, Shadowar, we noticed that your request did not mention the name of Jesus. It's important to remember that it is only by His name that we have access to God. Acts 4:12 WEB tells us, "There is salvation in no one else, for there is no other name under heaven that is given among men, by which we must be saved." If you haven't already, we encourage you to put your faith in Jesus Christ for salvation and for your daily needs.
