Your honest desire to draw near to God and to call Jesus Lord is itself evidence of the Holy Spirit already at work in you, for no one can genuinely confess that Jesus is Lord except by the Holy Spirit. That confession is not something you produce on your own, it is the Spirit drawing you, convicting you, and dwelling within you.
Scripture says we know that He abides in us by the Spirit which He has given us. When you trusted in Christ, you were sealed with the Holy Spirit of promise, who is the down payment and guarantee of your inheritance until the full redemption comes. That seal is God's mark of ownership on your life, a sign that you belong to Him. Because of that, you can be confident that He will not get fed up with you and will not forsake you. His mercies are new every morning, as Lamentations teaches, and His forgiveness is not measured out mathematically but flows from His gracious character. When you confess your sin, He is faithful and just to forgive you through Jesus Christ alone, who is the only way of salvation.
You mentioned Moses and the promised land and the fear of missing what God has for you. God is merciful and patient, and His desire is to bring you into all that He has promised. Your part is to keep sowing to the Spirit, for Jesus said His words are spirit and life, and if we sow to the Spirit we will reap life everlasting. To sow to the Spirit means to stay in the Word, to pray, to yield to His leading, and to be filled with the Spirit continually. The Spirit who lives in you, for your body is His temple, wants to do more than simply indwell you, He wants to fill you and overflow through you with power to live in a way that pleases God.
You asked for the Holy Spirit to gently guide you into right choices and a life pleasing to Him. That is exactly His ministry. Jesus said when the Holy Spirit comes He will teach you all things, He will bear witness of Jesus, and He will convict and guide concerning righteousness. He also gives you power to put to death the deeds of the flesh, which you cannot do in your own strength. As you yield to Him and are controlled by Him, He perfects the love of God in you, and that love is more enduring and more important than any spiritual gift, though the Spirit does distribute gifts as He wills for the good of all.
God went about doing good and healing through the power of the Holy Spirit in the ministry of Jesus, and He poured out that same gift on both Jews and Gentiles who believed, showing that His grace is for all who call on Christ. He is still the one who brings healing and provision. He cares about your financial, spiritual and emotional needs, and He cares about your beloved dog as well.
I pray with you now that the Father, in the name of Jesus, would assure your heart of His fresh mercy and complete forgiveness, that you would know deeply that you are sealed and kept by His Spirit and not cast aside. I pray that He would fill you anew with His Holy Spirit, make you sensitive and open to His leading, teach you through His Word, and give you strength by the Spirit to turn from what displeases Him and to walk in what is right. I pray that He would provide for your needs, strengthen you spiritually and emotionally, and not let you be forsaken but keep you close to Himself. I pray also for full recovery and healing for both you and your dog according to His gracious will, and that His love would be perfected in you as you follow Jesus day by day. Amen.
