True Christianity can be summed up as 'Jesus only, Jesus always'. Why is this? This is because Christ alone is all-sufficient. If we have Him we have everything. If we are in Christ, then God has blessed us with "every spiritual blessing" (Ephesians 1:3). If we have Christ we need not look anywhere else for anything, all we need for all eternity is found in Him. We dishonour Him as the all-sufficient Saviour if we are looking for satisfaction anywhere else other than Him, if we are putting our trust for anything anywhere else. Here's what the reformer John Calvin has to say:
We see that our whole salvation and all its parts are comprehended in Christ. We should therefore take care not to derive the least portion of it from anywhere else. If we seek salvation, we are taught by the very name of Jesus that it is of him. If we seek any other gifts of the Spirit, they will be found in his anointing. If we seek strength, it lies in his dominion; if purity, in his conception; if gentleness, it appears in his birth. For by his birth he was made like us in all respects, that he might learn to feel our pain. If we seek redemption, it lies in his passion; if acquittal, in his condemnation; if remission of the curse, in his cross; if satisfaction, in his sacrifice; if purification, in his blood; if reconciliation, in his descent into hell; if mortification of the flesh, in his tomb; if newness of life, in his resurrection; if immortality, in the same; if inheritance of the Heavenly Kingdom, in his entrance into heaven; if protection, if security, if abundant supply of all blessings, in his Kingdom; if untroubled expectation of judgment, in the power given to him to judge. In short, since rich store of every kind of good abounds in him, let us drink our fill from this fountain, and from no other.John Calvin, Institutes, 2.16.19.
