Your prayer reflects a heart that wants to be faithful on two fronts at once, and that is exactly the wisdom of Ecclesiastes 7:18, to take hold of one thing without letting go of the other. You are asking for grace to keep interceding for your wife and your child while also giving your full attention to the new work God is putting before you, and God is able to give that grace. His mercies are new every morning and His faithfulness does not fail, as Lamentations 3:23 reminds us, so you can trust Him with both the past you cannot change and the present needs that press on you now.
I join you in praying for your wife, that God would grant true repentance that leads to life. Scripture shows that repentance is not just words or sorrow, but a real change that is seen in fruit. John preached a baptism of repentance where going down into the Jordan pictured dying to the old life and rising to walk in a new one, and he told even religious people not to trust in heritage or family background but to bring forth fruit that proves the heart has turned. That is what we ask for her, not a temporary change or outward form, but that she would see her need, turn from sin, and put her full trust in Jesus Christ alone for salvation. His name itself means Yahweh is salvation, and He came to save His people from their sins. There is no other hope, and now is the accepted time, now is the day of salvation. We pray that God would open her eyes to that and draw her to Himself.
For your young child, we pray with the same confidence in God's care. The Scriptures teach that God knows the child even in the womb, and that He delights to give good gifts, how much more the Holy Spirit to those who ask Him as Luke 11:13 says. We ask that this little one would be protected, directed into the love and character of Jesus, nourished on the Word from an early age as 2 Timothy 3:15 describes, and brought up in the instruction and admonition of the Lord according to Ephesians 6. Jesus taught that we must become humble like a little child and that to receive such a child in His name is to receive Him, and He warned against despising one of these little ones. That tells us how precious children are to Him and how important it is to minister to them. Training a child is systematic, patient work, like teaching a child to walk. You expect stumbling, you guard and guide, you correct in love, and you recognize the unique way God has made that child. We pray you will have wisdom to teach not just rote prayers but a real heart communion with God, and that the child will learn to respect godly authority and grow in faith. While the faith of a believing parent brings a holy covering over the home, each child still needs personal faith in Christ, and we pray God will work that by His grace.
At the same time we pray for what you called the new, that God would do a new thing as Isaiah 42 and 43 promise, and give you wisdom and strength to set things in order, to strengthen what remains, and to meet every pressing need as Titus teaches. God is sovereign over all the details, even moving an empire to bring Mary and Joseph to Bethlehem to fulfill prophecy, so you can trust Him to arrange the doors that need to be opened for Bible studies, prayer, and sharing the gospel with the lost. As Exodus 14:14 says, the Lord will work as you keep your trust in Him, and He will empower you to glorify Him and reflect His image, which you could never do in your own strength.
We pray that your running would be with purpose, as Paul says in 1 Corinthians 9:24, running to win, and in Philippians 3, forgetting what lies behind and pressing toward the upward call in Christ, and in Hebrews 12, laying aside every weight and distraction and fixing your eyes on Jesus to run the race marked out for you. That means both continuing to intercede and also moving forward with new evangelism, encouragement, discipleship, fellowship with the body of Christ, and diligent study of the Word. Ask God for wisdom as James 1:5 invites, listen for the Shepherd's voice as in John 10, and follow the leading of the Holy Spirit as in Romans 8.
Finally we join you in asking for protection, that God would keep you from temptation, from sin and evil, from evil people and from the evil one, as Jesus taught us to pray in Matthew 6 and John 17, and that He would cover you under His wings according to Psalm 91. May He guard your heart, guide your steps, and keep you abiding in Christ, bearing fruit that remains, for His glory. In Jesus' name we ask this.
