We understand that you feel weary and disheartened, but we want to remind you that God's word tells us to not grow weary in doing good, for in due season we will reap, if we do not give up Galatians 6:9 WEB.
Firstly, we notice that you did not mention praying or addressing this situation in the name of Jesus Christ. You should know that God does not hear sinners but if anyone is godly and does his will that he listens to him. Further, it is only by the name of Jesus Christ that we can approach God the Father. It is also only by the name of Jesus that we can be saved. Let us discuss this further.
You have not been hidden from God's sight, and He knows your struggles. In Psalm 34:18 WEB, it is written, Yahweh is near to those who have a broken heart, and saves those who have a crushed spirit. Even in your feelings of despair, God is close to you. Remember that we only have access to God in the name of Jesus Christ. Do not neglect this important fact.
Feeling that life is pointless is a common emotion when we feel overwhelmed, but remember that in Jesus Christ, there is always hope. As it is written in Jeremiah 29:11 WEB, For I know the thoughts that I think toward you, says Yahweh, thoughts of peace, and not of evil, to give you hope in your latter end.
Although you feel too old, too tired, and too far gone, God's grace is sufficient for you. His power is made perfect in weakness. So, I will boast all the more gladly in my weaknesses, that the power of Christ may rest on me 2 Corinthians 12:9 WEB.
Regarding your feelings of pointlessness, we must remember that God has a purpose for each one of us. In Ephesians 2:10 we are reminded of this. For we are his workmanship, created in Christ Jesus for good works, which God prepared before that we would walk in them. It is only in the name of Jesus Christ that this can be manifested in your life.
Let us pray together:
Dear Heavenly Father,
We come before You in the name of Jesus Christ, lifting up our brother/sister who feels weary and disheartened. We ask that You speak to them, Lord, and remind them of Your unfailing love and faithfulness. Give them the strength to persevere and to not grow weary in doing good. In the name of Jesus Christ, we rebuke any spirits of heaviness, despair, or hopelessness that may be influencing their thoughts and emotions. Help them to fix their eyes on You, the author and perfecter of our faith. In Jesus Christ's name, we pray. Amen.
Lastly, we want to remind you that you should not neglect meeting with the saints as some do. This is a very important part of a Christian's walk with God. This will encourage you to see how God is working in the lives of others and to let them know how you can pray for them. It is only in the name of Jesus Christ that we can approach God.
We urge you to continue praying and believing in the power of prayer. Even when we feel like giving up, God is still working behind the scenes. Keep holding on to His promises, and do not forsake the fellowship of the brothers and sisters in Christ. This is very important.
