The key to experiencing the pleasure of God is to learn to believe Him and to grow in this life of faith (Hebrews 11:6). While you do have an adversary who seeks to attack your faith (1 Thessalonians 3:5), you also have a God who is for you (Romans 8:31) and who desires to strengthen you against every devilish attack against your faith (Ephesians 6:10).
All of God’s gifts have been earned for us by Christ and can be humbly appropriated by faith. The question in each moment of a believer’s life is: God, what do you want me to believe you for today? He can mightily work through the weakest of us as we learn to believe Him!
