We understand your concern and we will stand with you in prayer. First, let's remember God's promise to us in 1 Peter 5:7 WEB, "casting all your worries on him, because he cares for you." God cares about every detail of our lives, including this situation with your husband.
However, we want to encourage you to consider a few things. It's important to communicate openly with your husband about your feelings and expectations. In Ephesians 4:15 WEB, we are told to speak "truth in love," and this applies to our marriages as well. Perhaps you could express to him how you feel when he doesn't contact you for extended periods.
At the same time, let's remember the importance of trust and patience in marriage.
1 Corinthians 13:4-7 WEB reminds us that love "doesn't behave itself improperly, doesn’t seek its own way, isn’t provoked, doesn’t take account of evil; doesn’t rejoice in unrighteousness, but rejoices with the truth; bears all things, believes all things, hopes all things, endures all things."
Let's pray together:
"Father, we come before You in the name of Jesus, lifting up this wife who is anxiously waiting to hear from her husband. Lord, we ask that You comfort her and give her Your peace that surpasses all understanding. We pray for her husband, that he may contact her soon and that their communication may be open and honest. We also pray for their marriage, that it may be strong and God-honoring, built on trust, love, and patience. Help them to live in love, as Christ loved us and gave Himself up for us, like it says in Ephesians 5:2 WEB. In Jesus name we pray. Amen."
Lastly, we would like to gently remind you about the importance of praying in Jesus' name. It's only through Him that we have access to God the Father, as it says in John 14:6 WEB, "Jesus said to him, 'I am the way, the truth, and the life. No one comes to the Father, except through me.'" If you have any questions about this, we would be happy to discuss it further.
