As a senior in Christ, you cannot live in fear. You need to know that God will be with you no matter what. But, such wisdom only comes when we read and meditate His word. So, here are some powerful Biblical scriptures.
Bible Verses
From John 21:15-22:
When they had finished breakfast, Jesus said to Simon Peter, “Simon, son of John, do you love me more than these?” He said to him, “Yes, Lord; you know that I love you.” He said to him, “Feed my lambs.” He said to him a second time, “Simon, son of John, do you love me?” He said to him, “Yes, Lord; you know that I love you.” He said to him, “Tend my sheep.” He said to him the third time, “Simon, son of John, do you love me?” Peter was grieved because he said to him the third time, “Do you love me?” and he said to him, “Lord, you know everything; you know that I love you.” Jesus said to him, “Feed my sheep. Truly, truly, I say to you, when you were young, you used to dress yourself and walk wherever you wanted, but when you are old, you will stretch out your hands, and another will dress you and carry you where you do not want to go.” (This he said to show by what kind of death he was to glorify God.) And after saying this he said to him, “Follow me.
From Psalm 118:
A Song of Victory
O give thanks to the Lord, for he is good; his steadfast love endures for ever! Let Israel say, ‘His steadfast love endures for ever.’ Let the house of Aaron say, ‘His steadfast love endures for ever.’ Let those who fear the Lord say, ‘His steadfast love endures for ever.’ Out of my distress I called on the Lord; Lord answered me and set me in a broad place. With the Lord on my side I do not fear. What can mortals do to me? The Lord is on my side to help me; I shall look in triumph on those who hate me. It is better to take refuge in the Lord than to put confidence in mortals. It is better to take refuge in the Lord than to put confidence in princes. All nations surrounded me; in the name of the Lord I cut them off! They surrounded me, surrounded me on every side; in the name of the Lord I cut them off! They surrounded me like bees; they blazed like a fire of thorns; in the name of the Lord I cut them off! I was pushed hard, so that I was falling, but the Lord helped me.
The Lord is my strength and my might; has become my salvation.
There are glad songs of victory in the tents of the righteous: ‘The right hand of the Lord does valiantly; the right hand of the Lord is exalted; the right hand of the Lord does valiantly.’ I shall not die, but I shall live, and recount the deeds of the Lord. The Lord has punished me severely, but he did not give me over to death. Open to me the gates of righteousness, that I may enter through them and give thanks to the Lord. This is the gate of the Lord; the righteous shall enter through it.
I thank you that you have answered me and have become my salvation. The stone that the builders rejected has become the chief cornerstone. This is the Lord’s doing; it is marvellous in our eyes. This is the day that the Lord has made; let us rejoice and be glad in it. Save us, we beseech you, O Lord! O Lord, we beseech you, give us success!
Blessed is the one who comes in the name of the Lord. We bless you from the house of the Lord. The Lord is God, and he has given us light. Bind the festal procession with branches, up to the horns of the altar. You are my God, and I will give thanks to you; you are my God, I will extol you. O give thanks to the Lord, for he is good, for his steadfast love endures for ever.
