He has provided us with absolutely everything so that we can live fully here on earth and an eternal life with Him forever, here we have a source of strength that is inexhaustible.
16 And I will pray the Father, and he will give you another Helper, to be with you forever; 17 even the Spirit of truth; whom the world cannot receive, because it neither sees him nor knows him; but you know him, because he dwells with you and will be in you.
John 14:16-17
Let us remember the picture of the last supper of the Lord Jesus Christ who at one point set out to teach the disciples what their mission was and what would happen after being crucified on the cross, the Lord Jesus Christ knew exactly what moment was ahead and that the darkest moment of humanity would arrive to begin a new era in the world. That is why immediately after speaking all this, He promised that He would send the Holy Spirit, the helper that would accompany them at all times, especially in future afflictions.
Generally, as human beings we believe that with our strength we will face and overcome all the tests we face in this life, this is something heroic, but when we choose the security we have in the Lord Jesus Christ we begin to develop a very different mentality, a mentality in accordance with the word of God. Thus we discover our human weakness, that we cannot face many tests that are presented to us, but at the same time we discover our strength through the Holy Spirit of God in us and we find more strength than we can understand, even than we can imagine to overcome any test.
Whether we face a physical, emotional or spiritual struggle, it is the Holy Spirit of God that will be helping us at all times, for that we have to put our trust in God that it will be so. The apostle Paul teaches us in detail how this is, let us remember the prayer of the apostle Paul who asked that this test be removed, while the Lord answered him that power would be perfected in weakness.
And he said to me, My grace is sufficient for you, for my power is made perfect in weakness. Therefore I will boast all the more gladly about my weaknesses, so that Christ's power may rest upon me.
2 Corinthians 12:9
