In moral application, dry ground is faith in and obedience to the precious Word of God. The Bible is solid, unchangeable and the only safe place on which to base your life and the decisions you make. "my words shall not pass away" (Luke 21:33). A solid foundation on which to build a beautiful, lifetime relationship with another can only be built safely on the dry ground of the unchanging Word of God.
Faith trusts God alone to provide wisdom and guidance for your courtship. "Without faith it is impossible to please Him" (Heb. 11:6). Obedience is the natural effect of faith in God and love for the Lord Jesus. "If ye love me, keep my commandments" (John 14:15).
Faith is increased, strengthened and guided by daily prayer and reading the Bible. "That your faith should not stand in the wisdom of men, but in the power of God" (1 Cor. 2:5). Are you questioning if you have enough faith? Read Luke 17 beginning with verse 5 (where the disciples asked the Lord to increase their faith).
