Jacob, Leah and Rachael. Leah was in a loveless marriage because of custom and deceit – the oldest daughter would marry first, and Jacob was tricked. Jacob loved Rachael who was the younger daughter. There are quite a few points which arise from this passage.
Marriage should be between one man and one woman. If polygamy is allowed, there is a good chance someone will be left out.
If we do things because of man-made customs, we could be doing things for the wrong reason. For example, if I go to church because I have always gone to church, it might become a drudgery and disliked. It would also mean I would be deceiving myself, as the reason for doing good (e.g. going to church) should not be because of any attempt to make myself presentable to God, as such a thing is impossible.
If we do things out of love, it will usually be enjoyable. Jacob laboured for seven years, yet because he loved Rachael, it passed very quickly. For me, it would mean that, because I love God, I would do what God wants, e.g. enjoy going to church to hear the Word of God and to meet with God’s people.

The evening’s sermon was related to the morning one, even though it was a different church and different preacher. The apostle Paul prayed to God about everything from the smallest to the greatest things. He prayed to the Father, asking for strength through the Spirit, that we may know the love of Christ. He asked that those who had faith in Christ would know the love that surpasses knowledge. That we would know how wide and deep is that love. Ultimately, because God loves us, we would love God.
