For other foundation - It is “implied” by the course of the argument here, that This was the foundation which had been laid at Corinth, and on which the church there had been reared. And it is affirmed that no other foundation can be laid. A foundation is that upon which a building is raised; the foundation of a church is the doctrine on which it is established; that is, the doctrines which its members hold - those truths which lie at the basis of their hopes, and by embracing which they have been converted to God

Ecclesiastes 7

11 For no other foundation can anyone lay than that which is [already] laid, which is Jesus Christ (the Messiah, the Anointed One).
12 But if anyone builds upon the Foundation, whether it be with gold, silver, precious stones, wood, hay, straw,
13 The work of each [one] will become [plainly, openly] known (shown for what it is); for the day [of Christ] will disclose and declare it, because it will be revealed with fire, and the fire will test and critically appraise the character and worth of the work each person has done.

John 14:6
To come to the Father is to obtain his favor, to have access to his throne by prayer, and finally to enter his kingdom. No man can obtain any of these things except by the merits of the Lord Jesus Christ.

As he was praying - Luke has taken notice of our Saviour‘s praying often. Thus, at his baptism Luke 3:21; in the wilderness Luke 5:16; before the appointment of the apostles, he continued all night in prayer Luke 6:12; he was alone praying Luke 9:18; his transfiguration also took place when he went up to pray Luke 9:28-29.

Teach us to pray - Probably they had been struck with the excellency and fervor of his prayers, and, recollecting that “John” had taught his disciples to pray, they asked him also to teach “them.” We learn, therefore:

1.That the gifts and graces of others should lead us to desire the same.

2.That the true method of praying can be learned only by our being properly taught. Indeed, we cannot pray acceptably at all unless God shall teach us how to pray.

3.That it is proper for us to meditate beforehand what we are to ask of God, and to arrange our thoughts, that we may not come thoughtlessly into his presence.

John 15:4
Abide in me - Remain united to me by a living faith. Live a life of dependence on me, and obey my doctrines, imitate my example, and constantly exercise faith in me.

Psalms 130
Out of the depths - The word rendered “depths” is from a verb - עמק ‛âmaq - which means to be deep; then, to be unsearchable; then, to make deep; and it would apply to anything low, deep, or profound, as the ocean, a pit, or a valley. The word used here occurs elsewhere only in the following places: Psalm 69:2, Psalm 69:14, where it is rendered “deep,” applied to waters; and Isaiah 51:10; Ezekiel 27:34, where it is rendered “depths.” The word, as used here, would be applicable to deep affliction, dejection, or distress. It would be applicable
