There are three stages in God's plan of salvation: justification (initial acceptance by God), sanctification (ongoing growth in holiness), and glorification (final perfection in Heaven). While all Christians are equal at the foot of the cross, not all progress equally in their spiritual journey. The story of Caleb in Numbers 13-14 illustrates the importance of fully surrendering to God, following Him throughout one's entire life, and living by the power of the Holy Spirit. These qualities set Caleb apart and enabled him to enter the Promised Land when others could not. As Christians, we are called to this same level of commitment and reliance on God's Spirit to fulfil His purpose for our lives.
